Abstract

Helium nanodroplets are ideal testbeds for elucidating secondary processes induced by ionizing radiation in condensed matter. Here we study photoionization electron spectra of large He nanodroplets in the extreme ultraviolet region, where photoelectrons undergo multiple inelastic collisions with He atoms in the nanodroplets. The resulting characteristic electron energy-loss features are identified by their dependence on photon energy and nanodroplet size and by comparison with a simple numerical simulation. Conditions for minimizing electron scattering with the He nanodroplets are discussed.

Effect of deuteration on methane cluster stability

The evaporation from clusters of mixed deuterated and protonated methane molecules has been studied experimentally and theoretically. Only loss of the two components CH$_4$ and CD$_4$ is observed, showing the absence of hydrogen scrambling. The branching ratio of the two channels scales with the mole fractions of the isotopologues, corresponding to a fixed ratio of 1.5 for the CH$_4$ and CD$_4$ rates. The number is explained by the combined effect of the zero-point energies found in quantum chemical calculations and the use of detailed balance to describe the evaporation process, the latter by incorporating the moment of inertia of the two isotopologue molecules and their rotational degrees of freedom. The difference in evaporative activation energies is determined to be 6.1~\% and 6.8~\% from two experimental determinations and 8.7~\% theoretically with B3LYP+GD3BJ, corresponding to 5--7~meV. The same theory finds the CH$_4$ activation energy to be 83.8 meV, close to the experimental bulk value of 84.7 meV. Differences in Helmholtz free energies of decay products are extracted from the experimental data, yielding the molecular mixing as the only contribution to the entropy term.

Model potential based estimation of positron bound states with polar molecules

Positron forming a bound state with molecules is an area of meticulous research and remains open to simpler techniques for estimating the binding energy. Correlation between the incoming positron and the molecular electrons plays a crucial role even for polar molecules, where binding is also possible at the static-potential level. In this work, we have used a model correlation potential, which accounts for the virtual positronium formation, in the single-center expansion scattering calculations for polar oxygen-containing molecules. The thus determined S-matrix is continued into the complex momentum plane by fitting it to the Pade approximant. The positron bound state is estimated using the calculated pole position of the S-matrix. The results, compared with the latest experimental and ab initio findings, look quite promising.

Hydrogen isotope mixing entropy in ammonia clusters

Measured evaporation branching ratios of partially deuterated isotopologues of protonated ammonia clusters (NH$_3$)$_N$ H$^+$ ($N \geq 8$) show ratios that depend only on the clusters' deuterium mole fraction. This demonstrates randomly distributed protium and deuterium in the molecules and can be used to determine free energy differences in the product cluster. The entropy thus determined is exclusively the deuterium-protium mixing entropy. The relative dissociation energies of the four isotopologues are determined and with the support of quantum chemistry calculations, their absolute values are estimated.
