Abstract
The research on the (n, γ) cross section of selenium isotope 74Se, determined using the activation method, has potential applications that could pique your interest. The irradiation was conducted by a Bremsstrahlung photon beam generated by an electron medical accelerator, yielding neutrons within an energy spectrum ranging from 1 keV to 1 MeV. The production of 75Se nuclei occurs through a combination of neutron capture and photonuclear reactions in the field of a medical linear accelerator. Both the photon- and neutron-induced contributions had to be studied. Photo- and neutron-capture cross sections of 74Se were calculated using the TALYS 2.0 nuclear reaction code and compared with our measurement. The results show that this method could be employed to study reactions relevant to nuclear astrophysics in medical centers, opening up new avenues for research and application.
