Abstract
Residual activities produced via35Cl or32S beams in thin112Sn and106Cd targets have been studied by γ-ray and X-ray spectroscopy techniques behind a He-jet system. Mass identification of the products has been performed by coupling the He-jet to the medium current ion source of an isotope separator. Neutron-deficient nuclei with 137≦A≦144 have been identified. Decay schemes of several new isotopes as138Eu (12s),141Gd (22s),143Tb (12s and <17s),144Dy (9s) and possibly140Gd (11s) have been derived. New informations have also been provided for137Sm (45s),139Eu (24s) and144Tb (5s). Data have been presented through systematics. The shapes of these nuclei and their trends versusN andZ have been analysed.
