Nuclear Data Sheets for A = 141

Nuclear spectroscopic information for experimentally investigated nuclides of mass 141 (Te, I, Xe, Cs, Ba, La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, and Ho) has been evaluated. A summary of information obtained in various reaction and decay experiments is presented, together with data tables and adopted level schemes.

The Study of (n, 2n) Reaction Cross Sections for Ce and Nd Isotopes up to 20 MeV

Neutron cross section calculations for {sup 136}Ce(n, 2n){sup 135}Ce, {sup 138}Ce(n, 2n){sup 137}Ce, {sup 140}Ce(n, 2n){sup 139}Ce, {sup 142}Ce(n, 2n){sup 141}Ce, {sup 142}Nd(n, 2n){sup 141}Nd, {sup 144}Nd(n, 2n){sup 143}Nd, {sup 146}Nd(n, 2n){sup 145}Nd, {sup 148}Nd(n, 2n){sup 147}Nd, and {sup 150}Nd(n, 2n){sup 149}Nd were done in the incident energy range from 10 to 20 MeV. The calculations were performed using three codes TALYS-1.6 for two-component Exciton model, EMPIRE-3.2 Malta for Exciton model, and ALICE/ASH for the Geometry-Dependent Hybrid (GDH) model. The results of model calculations were compared with the available experimental data and also with the evaluated data in the TENDL-2015 (based on the modified TALYS code), ENDF/B-VII.1 libraries. The calculated cross section data were compared with the available experimental data obtained from EXFOR and also compared with semiempirical formulas around 14–15 MeV. The results of model calculation were found to be in good agreement with the experimental data given in literature and semiempirical data around 14–15MeV.
