States inPt197populated by the (d,p), (d,t) and (n,γ) reactions

Abstract
States in Pt197 have been studied using the Pt196(d,p)Pt197 and Pt198(d,t)Pt197 reactions with 13.5 MeV deuterons and the Pt196(n,γ) reaction using thermal neutrons. The measured Q values were 3.606 ± 0.020, - 1.221 ± 0.020, and 5.8463 ± 0.0004 MeV for the (d,p), (d,t), and (n,γ) reactions, respectively. Transferred l values have been determined from angular distributions and spectroscopic factors determined by comparison with distorted-wave Born-approximation calculations. Some of the states can be tentatively assigned as Nilsson states arising from an oblate deformation. These include the 5/2[532], decoupled 1/2+[600] and 9/2+[615] states. A number of low lying states with l=1 cannot be explained using the Nilsson model or the shell model.
