INTEGRAL YIELDS OF PHOTONEUTRON REACTIONS ON TIN ISOTOPES 118Sn AND 124Sn IN THE NEAR-THRESHOLD ENERGY REGION

The integral yields of the photonuclear reactions 118Sn(,n)117mSn and 124Sn(,n)123mSn, which are of interest for studying scenarios of the formation of atomic nuclei in stars, are measured in the near-threshold energy region. The experimental data are compared with the results of theoretical calculations performed using the TALYS nuclear reaction code. The dependence of theoretical predictions on the choice of models of the nuclear level density and the radiative strength function is investigated.
