Abstract

The rigid triaxial rotor plus particle model (RTRP) was applied to the nucleus 125Xe in order to determine the value of the γ deformation. Two quantities are very sensitive to the γ deformation: the signature splitting of Yrast levels for negative parity levels (h1 1 2) and the lifetime of the (I= 7 2+, K= 7 2) isomer for positive parity lev els. From the two analyses one obtains the same value for the deformation γ=24°.
