Abstract

The (n,2n) reaction cross sections of cerium isotopes have been experimentally measured at the neutron energy of 13.50 ± 0.15 MeV by using the method of activation and off-line γ-ray spectroscopy. The neutron energy was obtained from the D-T reaction using the Purnima Neutron Generator at BARC. The ^natCe sample was irradiated along with the gold and indium monitor foils. The cross sections of ¹⁴⁰Ce(n,2n)¹³⁹Ce and ¹⁴²Ce(n,2n)¹⁴¹Ce reactions were measured by using both the gold and indium as a monitor and then collapsed to get the best values of reactions cross sections. The uncertainties in the measured cross sections of ¹⁴⁰Ce(n,2n)¹³⁹Ce and ¹⁴²Ce(n,2n)¹⁴¹Ce reactions were determined using covariance analysis by considering uncertainties in various attributes. The measured values from the present work were compared with the literature data based on EXFOR compilation, evaluated data from different libraries and theoretically calculated values from TALYS-1.95 and EMPIRE-3.2.
