Abstract: High-spin states in 150Sm have been investigated with the OSIRIS spectrometer. An alternating parity (octupole) band was found to develop above spin I = 8. A crossing of the positive-parity sequence of the outupole band with an aligned two-quasiparticle band has been observed around spin I = 16. It is suggested that above spin I = 16 reflection asymmetric and symmetric shapes coexist in 150Sm.
