[en] A considerable amount of experimental works has been recently done on the light Cadmium isotopes. The main purpose of these studies was to search for Coriolis decoupling mechanism in a transitional region. Negative and positive parity bands occuring in ¹⁰⁵Cd, ¹⁰⁷Cd, ¹⁰⁹Cd, ¹¹¹Cd have been correctly reproduced within the rotor-plus-particle model using self-consistent prolate core single-particle states. The aim of the present work is using HI reactions, to search for the high spin states in ¹⁰³Cd where only two low-lying levels are known so far, from on-line radioactivity studies, and to check whether this theoretical description remains still satisfactory
