Excitation functions and isomeric ratios in the reaction130Te (?,xpyn) for ?-particle energies between 15 and 37 MeV

Abstract

The 13~ n) 133Xe, 13~ p) 133I, 13~ pn)132I and 13~ 7n)129Te excitation functions for alpha particle energies between 14.7 and 36.5 MeV are presented. Excitation functions for the last three reactions are measured for the first time and more consistent results for (7, n) are obtained. The isomeric ratios for the (e n,), (e, pn) and (e, an) reactions were deduced. Calculations based on different theoretical models of equilibrium and preequilibrium decay are compared with the experimental results and discussed. Acceptable presentation of the energy behavior of the measured isomeric ratios was obtained when higher angular momentum depletion for preequilibrium emitted particles was included. The absolute values of the isomeric ratios however remain overestimated. 25.70.Gh
