Abstract

States in ${}^{197}{Pt}$ have been studied using the ${}^{196}{Pt} (d, p) {}^{197}{Pt}$ and ${}^{198}{Pt} (d, t) {}^{197}{Pt}$ reactions with 13.5 MeV deuterons and the ${}^{196}{Pt} (n, γ)$ 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.
