Shape phase transition and phase coexistence in odd Sm nuclei

NUCLEAR STRUCTURE ^{146,147,148,149,150,151,152,153,154,155,156,157}Sm; calculated energies of ground-state band members using several collective rotor and vibrator models; deduced shape phase transition in odd-A Sm nuclei from experimental S(2n) values and experimental energies of ground-band members in even and odd-A Sm nuclei. ^150,152Sm; analyzed ground-state and β band members. ^151,153Sm; analyzed four collective bands in each nucleus; deduced phase coexistence of rotational and vibrational excitations in ¹⁵¹Sm.
