Neutron induced cross section measurements on gallium isotopes at neutron energy 14.90 ± 0.01 MeV and covariance analysis

The cross sections of the ⁶⁹Ga(n,p)⁶⁹Zn^m, ⁶⁹Ga(n,2n)⁶⁸Ga, ⁷¹Ga(n,p)⁷¹Zn^m, ⁷¹Ga(n,n′α)⁶⁷Cu and ⁷¹Ga(n,2n)⁷⁰Ga reactions had been measured at $14.90\pm 0.01\text{MeV}$ neutron energy with the ²⁷Al(n,α)²⁴Na as monitor reaction using Neutron Activation Technique. The data analysis was carried out using the latest decay data. Detail uncertainty propagation had been performed and the measured cross sections are reported with their uncertainties and correlation coefficients. The cross sections newly measured in the present work are compared with the earlier reported cross sections available in the EXFOR Database. The measured cross sections reported by various authors had also been studied and discussed in detail. Theoretical calculations had been performed from reaction threshold to 20 MeV and compared along with the evaluated files from ENDF/B-VIII.0 and JENDL-4.0.
