“…This incident beam imparted recoil velocity v/c ∼ 0.8% of the compound nucleus in the forward direction. For the experiment, the enriched 174 Yb target of thickness ∼ 750 µg/cm 2 , on a thick Ta backing foil of thickness ∼ 3 mg/cm 2 , was made by evaporation technique [10]. For a stopper, a self supporting thick Au foil of thickness ∼ 8 mg/cm 2 was used.…”

Lifetimes have been measured of the low-and intermediate-spins states in 188 Pt nucleus using the recoil distance Doppler shift technique at IUAC, Delhi. The nuclear states of interest were populated via 174 Yb(18 O,4n) 188 Pt reaction at a beam energy of 79 MeV provided by 15 UD Pelletron accelerator. The extracted B(E2) values show an increase up to 4 + state and then a near constant behavior with spin along yrast band, indicating change of the nuclear shape in 188 Pt at low spins. The average absolute β 2 = 0.20(3) obtained from measured B(E2) values matches well the values predicted by CHFB and IBM calculations for oblate (β 2 ∼ −0.19) and prolate (β 2 ∼ 0.22) shapes.
