DSAM LIFETIME MEASUREMENTS IN THE YRAST BAND OF ¹³¹<font>La</font> AND THE CHIRAL BANDS IN ¹³²<font>La</font>

Abstract

Lifetimes of the h 11/2 decoupled band in 131 La and supposed chiral bands in odd-odd 132 La have been measured using the Doppler Shift Atenuation method. The properties of all bands have been calculated in terms of the Core Quasi Particle Coupling and Core Particle Hole Coupling models by using in both cases the same phenomenological core of 130 Ba . A new band in 132 La has been found.
