Nuclear fusion induced by X-rays in a crystal

The nuclei that constitute a crystalline lattice, oscillate relative to each other with a very low energy that is not sufficient to penetrate through the Coulomb barriers separating them. An additional energy, which is needed to tunnel through the barrier and fuse, can be supplied by external electromagnetic waves (X-rays or the synchrotron radiation). Exposing to the X-rays the solid compound LiD (lithium-deuteride) for the duration of 111 hours, we have detected 88 events of the nuclear fusion d+Li6 ---> Be8*. Our theoretical estimate agrees with what we observed. One of possible applications of the phenomenon we found, could be the measurements of the rates of various nuclear reactions (not necessarily fusion) at extremely low energies inaccessible in accelerator experiments.

Peculiarities of localization of several sonoluminescent bubbles in spherical resonators

Experiments on generation of 1, 2, 4, and 6 sonoluminescent bubbles in water with an external ultrasound source in an acoustic sphere resonator with glass walls have been carried out. Theoretical examination has shown that the observed excitation frequencies could be described with a good accuracy taking into account that the velocities and pressures of the contacting media on the external and internal resonator surfaces are equal. The necessity of accounting for oscillations with non--zero self--values of angular momentum operator has been shown when describing the features of localization of several bubbles. To explain a strangely small distance between the bubbles in the case of two--bubble sonoluminescence the following possible explanations have been proposed: a) mechanism of space splitting of a mode with a singular angular momentum and b) mechanism of secondary excitation when one of the bubbles is trapped into the acoustic trap created by high--frequency vibrations arising simultaneously when the other bubble sonoluminescence occurs.

Trap Activation Energy and Transport Parameters of HgI$_2$ Crystals for Bubble-Plasma Diagnostics

In recent data on neutron induced acoustic cavitation in deuterium--containing liquids obtained by neutron measurements it was shown that very high temperatures could arise in some special cases. To study temperature of so--called bubble plasma it is desirable to have micro--detectors of X-rays, which can be prepared on the basis of room--temperature semiconductor detectors, in particular on mercuric iodide ($α$--HgI$_2$) crystals. Having in view this aim, the properties of gel--grown ($α$--HgI$_2$) crystals was studied by means of isothermal currents, and trap parameters was estimated. Results are promising for special aim of preparing X-ray detectors with moderate energy resolution needed in bubble--plasma diagnostic, though improving of crystal growing technology is necessary. {\it PACS:} 29.40.Wk; 52.70.La {\it Keywords:} X-ray and gamma--ray measurements; semiconductor detectors; mercuric iodide; plasma diagnostics; cavitation

Search for Nuclear Reactions in Water Molecules

A possibility for molecular-nuclear transitions to occur was recently predicted for some few-atomic systems. Among others, the molecule of ordinary water was shown to be a candidate for this effect due to a presence of (1-, 4.522 MeV) resonance in 18Ne nucleus. A search for traces of nuclear reactions was carried out for condenced and vaporous phases of water, with the use of low-background annihilation spectrometry. The measurements were performed under conventional conditions and under conditions of the Baksan Neutrino Observatory.

Possibility for Teleportation of Nuclei

Experimental realizations of QT have so far been limited to teleportation of light. The present communication gives a new experimental scheme for QT of heavy matter. We show that the standard experimental technique used in nuclear physics may be successfully applied to teleportation of spin states of atomic nuclei. It was shown that there are no theoretical prohibitions upon a possibility of a complete Bell measurement, so that implementation of all four quantum communication channels is at least theoretically available. A general expression for scattering amplitude of two 1/2-spin particles was given in the Bell operator basis, and peculiarities of Bell states registration are briefly discussed.

Experimental search for molecular-nuclear transitions in water

Experimental search for molecular-nuclear transitions H_2O\to^{18}Ne^*(4.522,1^-)\to^{18}F\to^{18}O in water molecules was carried out. The measurements were performed in a low-background laboratory at the Baksan Neutrino Observatory. Under the assumption that the above transitions take place, the estimate for the half-life time of water molecule was found to be about 10^{18} years.

First Single Bubble Sonoluminescence in Dubna

At the Institute in Physical-Technical Problems experiments on sonoluminescence was started by our group at the beginning of 1998. The study was focused at properties of the SBSL, and the aim was to find more optimum conditions for a search for some recently predicted rare effects in SBSL- process.

Nuclear Teleportation

Until recently, only science-fiction authors ventured to use a term teleportation. However, in the last few years, on the eve of upcoming new millennium, the situation changed very much. The present report gives a synopsis of main concepts in this area. The readers will be able to make sure that paradoxical phenomena in the microcosm give a possibility to demonstrate the exchange of properties between microobjects, removed at a very large distance from each other, when no forces act between them. A new experimental scheme with hydrogen and helium nuclei is proposed. It is expected that the results of these experiments will be considered as teleportation of nuclear properties of atoms of the simplest chemical elements. A problem of teleportation of the more palpable cargo is left to the physics of the more distant future.

Experiments on Sonoluminescence: Possible Nuclear and QED Aspects and Optical Applications

Experiments aimed at testing some hypothesis about the nature of Single Bubble Sonoluminescence are discussed. A possibility to search for micro-traces of thermonuclear neutrons is analyzed, with the aid of original low-background neutron counter operating under conditions of the deep shielding from Cosmic and other sources of background. Besides, some signatures of QED-contribution to the light emission in SBSL are under the consideration, as well as new approaches to probe a temperature inside the bubble. An applied-physics portion of the program is presented also, in which an attention is being paid to single- and a few-pulse light sources on the basis of SBSL.
