Abstract

Energy spectra of inelastically scattered 16-MeV deuterons were measured at angles of 90° and 125° using enriched targets of

{}^{230}{Th}

,

{}^{240}{Pu}

,

{}^{244}{Pu}

, and

{}^{248}{Cm}

. In each nucleus the ground state band is observed up to and including the

J^{π} = 8^{+}

level. The

β

vibration

J^{π} = 0^{+}

level is identified in

{}^{230}{Th}

, and in this and the remaining three nuclei evidence for the

γ

vibration is discussed. At least three octupole bands are observed in each nucleus and

K

,

J^{π}

assignments are made in a number of cases.

B (E 2)

and

B (E 3)

values are extracted for selected levels.
