Lifetime measurements of the 31-, 51-, and 11- states in Nd144 show that the absolute E2 and E3 transition rates from the 51- and 11- states are consistent with their structure being formed by the coupling of the lowest quadrupole (21+) and octupole (31-) excitations. A level at 2205 keV has been identified as having Jπ=4- and may be another member of this quadrupole-octupole coupled quintuplet. The energy spacing of the quintuplet can be explained by anharmonicities in the quadrupole-octupole interaction and the influence of the ν2(2f72,1i132) configuration. © 1994 The American Physical Society.
