Investigation of neutron-deficient isotopes in the barium-region

Bombarding targets of 106Cd,¹⁰⁸Cd and¹¹⁰Cd with¹⁶O ions of 52.5–66.0 MeV neutron deficient barium, cesium and xenon isotopes were produced and have been studied using excitation functions and neutron-gamma, proton-gamma, alpha-gamma and gammagamma coincidence measurements. Partial level schemes for¹²³Ba and¹²¹Ba were proposed. A number of gamma transitions was assigned to the different product nuclei. The measured particle emission probabilities from the compound nuclei are compared with different evaporation models. The models mostly underestimate neutron emission and often overestimate the emission of alpha particles.
