Second order phase transitions from octupole-nondeformed to octupole-deformed shape in the alternating parity bands of nuclei around ²⁴⁰Pu based on data

NUCLEAR STRUCTURE ²³²Th, ²³⁸U, ²⁴⁰Pu; calculated potential energy of the octupole collective motion as function of β₃ parameter and angular momentum; analyzed levels, J, π, ground-state alternating parity bands. Supersymmetric quantum mechanics, two-center octupole wave functions ansatz, and Landau theory of phase transitions. Evidence for second order phase transition from reflection-symmetric to reflection-asymmetric shapes.
