Quasiparticle phonon model description of low-energy states in ¹⁵²Pr

RADIOACTIVITY ¹⁵²Pr(IT)[from ²⁴¹Am(n, F), E=thermal, followed by mass separation of A=152 fission fragments using Lohengrin separator at ILL-Grenoble]; measured Eγ, Iγ, ce, x rays, (A=152 ions)γ-coin, (A=152 ions)ce-coin, half-life of the isomer by (A=152 ions)γ(t), conversion coefficients. ¹⁵²Pr; deduced levels, J, π, multipolarities, configurations. Comparison with quasiparticle phonon model (QPM), combined with the particle-rotor model to include octupole correlations and Coriolis mixing. ¹⁵²Nd; calculated energies of the first two 3- levels in connection with β^- decay of ¹⁵²Pr g.s. to ¹⁵²Nd.
