Quasiparticle phonon model description of low-energy states in $^{152}$Pr
2018
Delayed γ -ray and conversion-electron spectroscopy is performed on A = 152 fission fragments, at the
Lohengrin spectrometer of the Institut Laue-Langevin, providing a new decay scheme for 152Pr. The quasiparticle
phonon model, combined with the particle-rotor model, which allows octupole correlations and Coriolis mixing
to be taken into account, is applied to analyze its low-energy structure. The main configurations are found to be
(π3/2[422] ⊗ ν5/2[642])1+ for the isomer and (π3/2[541] ⊗ ν3/2[521])3+ for the ground state
