Abstract

As a part of a thorough work of excitation functions of deuteron induced reactions, experimental cross-sections of ^{185,183m,183g,182}Os and ^{188,186,184m,184g,183}Re activation products on natRe were measured up to 40 MeV for the first time with the activation method using a stacked foil irradiation technique and high resolution \gamma-spectrometry. Comparison with the former results of other laboratories and with the predictions of the ALICE-IPPE and EMPIRE-3 model codes, modified for improved calculations for deuteron reactions, and with data in the TENDL-2011 library are also presented. Thick target yields were given deduced from our experimental cross-sections and compared with the few literature values. For practical applications (thin layer activation) also activity versus depth distributions were calculated for selected isotopes.
