Investigation of cross sections of deuteron induced nuclear reactions on selenium up to 50 MeV

In the frame of a systematic study of deuteron induced nuclear reactions on all elements, activation cross sections on $$^{\mathrm {nat}}$$ nat Se were investigated. Excitation functions were measured up to 50 MeV particle energy for production of $$^{\mathrm {82}}$$ 82 Br(m$$+)$$ + ) ,$$^{\mathrm {80m}}$$ 80 m Br, $$^{\mathrm {77}}$$ 77 Br(m$$+)$$ + ) ,$$^{\mathrm {76}}$$ 76 Br(m$$+)$$ + ) , $$^{\mathrm {75}}$$ 75 Br, $$^{\mathrm {75}}$$ 75 Se(cum), $$^{\mathrm {73}}$$ 73 Se(cum), $$^{\mathrm {76}}$$ 76 As,$$^{\mathrm {74}}$$ 74 As, $$^{\mathrm {73}}$$ 73 As(cum), $$^{\mathrm {72}}$$ 72 As and $$^{\mathrm {71}}$$ 71 As(cum) by using the activation method through stacked foil irradiation followed by off-line gamma-ray spectrometry. The experimental results were compared to the earlier experimental data and to excitation functions calculated with the ALICE-D and EMPIRE-D theoretical model codes and data given in the TENDL-2019 on-line library based on TALYS calculations.
