Cross-section measurements for 141Pr isotope at neutron energies from 13.5 to 14.8Â MeV

Cross-sections for (n,2n), (n,p), and (n,t) reactions have been measured on praseodymium isotopes at the neutron energies from 13.5 to 14.8 MeV using the activation technique in combination with high-resolution gamma-ray spectroscopy. Data are reported for the following reactions: 141Pr(n,2n)140Pr, 141Pr(n,p)141Ce, and 141Pr(n,t)139Ce. Nuclear model calculations using the code HFTT, which employs the Hauser-Feshbach (statistical model) and exciton model (precompound effects) formalisms, were undertaken to describe the formation of the products. The results were compared with previous data.
