The use of high-resolution gamma-ray spectrometers and a sectored single-crystal Compton polarimeter provided detailed information on excitation energies, spins, parities, decay widths, transition probabilities, and branching ratios of numerous new spin-1 states in Nd-144. The strong E1 excitation at 2185 keV in this N = 84 nucleus is interpreted as the quadrupole-octupole coupled two-phonon excitation which has been observed systematically in the neighboring N = 82 isotones. The decay properties of this 1(-) state are compared with the systematics of the low-lying 1(-) levels in the other even-even, stable Nd isotopes. The M1 excitations in Nd-144 are discussed with respect to the deformation dependence of the orbital M1 `'scissors mode,'' the so-called `'delta(2) law,'' which has been studied previously in the other stable even-even Nd nuclei and in the Sm isotopes.
