“…It can be seen that for the isomeric state the theoretical TALYS calculations based on three phenomenological level density models are in agreement with the results of N. L. Das et al [54] and W. D. Lu et al [55]. However, our results at 12.50, 15.79 and 18.87 MeV and reported data [56][57][58][59] are much higher than those of the three phenomenological models for the 121 Sb 120 Sb m reaction. The three phenomenological level density models for the 121 Sb 120 Sb g reaction are able to reproduce the reported experimental data very well within the experimental uncertainties.…”

“…In addition, the JENDL/AD-2017 and TENDL-2019 evaluations agree with the reported data of J. H. Mccrary et al [63] and Y. Kanda [65] at higher energies within experimental uncertainties. The cross section predicted by the JEFF-3.3 library is too large in the 15 MeV energy region agrees very well with lower energy data of N. L. Das et al [54], B. Minetti et al [57] and M. Bormann et al [59].…”

“…The TALYS calculations using microscopic level density models Goriely and Goriely -Hilaire for the 121 Sb 120 Sb m reaction are able to reproduce the experimental data of S. K. Ghorai et al [56], B. Minetti et al [57] and R. Pepelnik et al [58], within experimental uncertainties. It can be seen that, in the 13 to 18 MeV energy range, the results of S. K. Ghorai et al [56] and M. Bormann et al [59] are consistent with the results of TA-LYS calculations using the microscopic level density model Goriely -Hilaire -Gogny for the isomeric state, whereas for the ground state the Goriely and Goriely-Hilaire level density models calculations are in agreement with the existing experimental data. In addition, for the isomeric state the TALYS calculation using microscopic level density model Goriely -Hilaire -Gogny overestimated the cross section and agreed with the lower energies data of S. K. Ghorai et al [56] and M. Bormann et al (n, 2n) [59].…”

“…4(a), our results are higher than those obtained by N. L. Das et al [54], W. D. Lu et al [55] and A. Reggoug et al [66]. At 15.79 and 18.87 MeV, the present measured data are in agreement with the results of S. K. Ghorai et al [56] and M. Bormann et al [59] within experimental uncertainties. In contrast, at 12.50 MeV, the present data lies between the data of S. K. Ghorai et al [56] and Y. Kanda [65].…”

The cross sections of the 121Sb(n,2n) 120Sbm and 123Sb(n,2n) 122Sb reactions were measured at 12.50, 15.79 and 18.87 MeV neutron energies relative to the standard 27Al(n,α) 24Na monitor reaction using neutron activation and offline γ-ray spectrometry technique. Irradiations of the samples were performed at the BARC-TIFR Pelletron Linac Facility, Mumbai, India. The quasi-monoenergetic neutron was generated via the 7Li(p,n) reaction. Statistical model calculations were performed by nuclear reaction codes TALYS (ver. 1.9) and EMPIRE (ver. 3.2.2) using various input parameters and nuclear level density models. The cross sections of the ground and the isomeric state as well as the isomeric cross section ratio were studied theoretically from reaction threshold to 26 MeV energies. The effect of pre-equilibrium emission is also discussed in detail using different theoretical models. The present measured cross section were discussed and compared with reported experimental data and evaluation data of the JEFF-3.3, ENDF/B-VIII.0, JENDL/AD-2017 and TENDL-2019 libraries. A detailed analysis of the uncertainties in the measured cross section data was performed using the covariance analysis method. Furthermore, a systematic study of the (n,2n) reaction cross section for 121Sb and 123Sb isotopes were also performed within 14-15 MeV neutron energies using various systematic formulae. This work helps to overcome discrepancies in Sb data and illustrate a better understanding of pre-equilibrium emission in (n,2n) reaction channel.
