Abstract
The neutron induced reactions cross section of Tellurium (Te) isotopes has been investigated using the activation technique at Neutron and Ion Irradiation Facility (NIIF) at Institute for Plasma Research (IPR), Gujarat (India), by D-T fusion reaction. The present study focused on cross section of 122,124,126,128Te(n,p)122,124,126,128Sbg+m, 122,128,130Te(n,2n)121,127,129Teg and 122,124,130Te(n,2n)121,123,129Tem reactions. The irradiated sample (Te) was examined through an off-line γ-ray spectroscopy using a High Purity Germanium (HPGe) detector to measure the photopeak counts at characteristic γ-ray energies of the reactions. The measured cross section of (n,p) reactions vary from 11.17 mb to 0.63 mb with increasing mass number of Te. However, the range of cross section for (n,2n) reactions are between 400 and 850 mb. Moreover, covariance analysis has been carried out for detail assessment of uncertainties in reactions cross section. The present measured work is also compared with EXFOR data as well as evaluated data libraries such as ENDF/B-VIII.1, JEFF-3.3, JENDL-5 and TENDL-2023. Furthermore, theoretical calculations using TALYS 2.0 code have been executed to reproduce experimental measured cross section for (n,p) and (n,2n) reactions using default and optimal set of parameters.
