Abstract

In this study, the excitation functions of (n,2n) reactions for 30,32,34,35,37,38 Ba isotopes are calculated using TALYS 1.6, EMPIRE-3.2.2, and ALICE-GDH codes based on statistical model up to 20 MeV. Moreover, the cross section for each isotope have also been estimated at 14.2 MeV using semi empirical formula developed by four different authors. The calculated and estimated cross-sections are compared with experimental cross-sections from EXFOR and compared with the evaluation data in ENDF/B-VII.1 library. Results are close agreement with the experimental data from literature.

Highlights

The nuclear reaction models have been developed estimate the reaction cross-sections due to lack of experimental data [1,2,3,4]
The (n,2n) cross sections for Ba 30,32,34,35,37,38 isotopes were calculated from 10 MeV to 20 MeV neutron energies using TALYS 1.6, EMPIRE3.2.2, and ALICE
In this present work, (n,2n) reaction cross sections were theoretically calculated for the reactions 130Ba(n,2n)129Ba, 132Ba(n,2n)131Ba, 134Ba(n,2n)133Ba, 135Ba(n,2n)134Ba, 136Ba(n,2n)135Ba, 137Ba(n,2n)136Ba, and 138Ba(n,2n)137Ba at an incident neutron energy of 14.2 MeV using their different models up to 20 MeV

Summary

Introduction

The nuclear reaction models have been developed estimate the reaction cross-sections due to lack of experimental data [1,2,3,4]. The (n,2n) cross sections for Ba 30,32,34,35,37,38 isotopes were calculated from 10 MeV to 20 MeV neutron energies using TALYS 1.6, EMPIRE3.2.2, and ALICE.
