Determination of integral cross sections of 3H in Al foils monitors irradiated by protons with energies ranging from 40 to 2600 MeV

Results of t production in Al foil monitors are presented. These foils have been irradiated by protons of different energies in a range of 0.04 - 2.6 GeV. The irradiations were carried out at the ITEP accelerator U-10 under the ISTC Project 3266 during 2006 - 2009. t has been extracted from Al foils using an A307 Sample Oxidizer. The values of the Al(p,x)t cross sections obtained in these experiments are compared with data measured at other laboratories and with results of simulations by the MCNP6 radiation transport code using the CEM03.03 event generator.

Excitation functions of the nat-Ta(p,x)178m2Hf and nat-W(p,x)178m2Hf reactions at energies up to 2600 MeV

Due to potential level of energy intensity 178m2Hf is an extremely interesting isomer. One possible way to produce this isomer is irradiation of nat-Ta or nat-W samples with high energy protons. Irradiation of nat-Ta and nat-W samples performed for other purposes provides an opportunity to study the corresponding reactions. This paper pre-sents the 178m2Hf independent production cross sections for both targets measured by the gamma-ray spectrometry method. The reaction excitation functions have been obtained for the proton energies from 40 up to 2600 MeV. The experimental results were compared with calculations by various versions of the intranuclear cascade model in the well-known codes: ISABEL, Bertini, INCL4.5+ABLA07, PHITS, CASCADE07 and CEM03.02. The isomer ratio for the nat-Ta(p,x)178m2Hf reaction is evaluated on the basis of the available data.
