Abstract

On the basis of conversion electron andγ-angular distribution measurements new spin and parity assignments in138Ce have been made. They lead together with the already known lifetime of the 10+ yrast state whose parity was unclear to an extremely low transition probability of the 10+→8+ transition. A comparison with neighbouring even isotopes is made.
