The nucleus {sup 144}Sm has been studied with the ({ital n},{ital n}{prime}{gamma}) reaction and lifetimes of many states have been extracted from the observed Doppler shifts of the deexciting {gamma} rays. A large number of fast {ital E}1 transitions have been observed and have led to the identification of possible members of the octupole-octupole and the quadrupole-octupole multiplets. Substantial fragmentation of the two-phonon octupole strength is indicated.
