High angular momentum states in {sup 144}Nd are studied via the {gamma} rays produced in the {sup 130}Te({sup 18}O, 4{ital n}){sup 144}Nd reaction. In addition to the previously known sequence of states built on the 3{sub 1}{sup {minus}} state, we have observed another negative-parity sequence built on the 3395 keV 9{sup {minus}} state, which is apparently of a two quasiparticle nature. These two negative-parity sequences probably interact and mix significantly. The present {sup 144}Nd results raise questions regarding the interpretation of medium spin states of {sup 146}Nd in terms of strong octupole correlations.
