Spectroscopy of192Po

Abstract

Excitations in ${}^{192}$Po have been studied via in-beam $\ensuremath{\gamma}$-ray spectroscopy following the ${}^{164}$Er + 164 MeV ${}^{32}$S reaction. The experiment was performed at the ATLAS facility using ten Compton-suppressed Ge detectors and the Fragment Mass Analyzer. The $\ensuremath{\alpha}$ decay of ${}^{192}$Po has been used to identify prompt $\ensuremath{\gamma}$-ray transitions by means of the recoil decay tagging technique. The first three excited states of ${}^{192}$Po were established. The particle-core model has been successfully used to model these excitations and the quasiparticle random phase approximation has been applied to extract microscopic wave functions of the 2${}_{1}^{+}$ states.
