In beam spectroscopy and cross-section studies for the106Cd+12C reaction

Abstract

From classical in-beam spectroscopy on the l~ l zC reaction, unambiguous ?'-ray assignments have been done for 116Xe, 116I and 116Te nuclei. The ground band levels observed in l a6Xe have been compared to those of heavier even-even xenon isotopes and to the IBA theoretical predictions. In addition, using the new ?,-ray assignments, evaporation cross-sections of the ~aSxe compound nucleus have been estimated and compared to the evaporation model calculations.Nuclear Reactions: 1~ 12C, E=48-61 MeV; measured a(E; Ey, 0), ?

High-spin bands in117,119I and118Xe

“…The main obstacle for studies in this region is the complexity of the reaction, since protons, neutrons and alpha particles are emitted from the compound nucleus with comparable probabilities. See, for example, Table2 of Gizonet al [5], where six comparable cross sections were determined in the reaction ~2C+ l~ at E~ab=49MeV. In the present work we attempt to reach high-spin bands in nuclei around mass number A ~ 118.…”
