Abstract
The lifetimes of the gamma-ray continuum in144Gd were measured up to spin ∼ 50ħ via the DSAM technique following the74Ge(72Ge, 2n) reaction at 270 MeV beam energy. The average Doppler Shift of theE2 bump corresponds mostly to a structure with a deformation (β∼0.2–0.3), consistent with the triaxial structure predicted to lie close to the yrast line at spins 30–50ħ in this nucleus.
