The decay of radiochemically separated /sup 144/Ce source in equilibrium with /sup 144/Pr isomers has been reinvestigated with HPGe detectors. The energies and intensities of 19 ..gamma.. rays were measured, of which three are new. A /sup 144/Nd level scheme allows the incorporation of most of the transitions between 13 excited states. Levels at 2072.8 (2/sup +/), 2368.3 (2/sup +/), 2581.8 (3/sup +/), and 2742.8 (0/sup +/) keV, observed earlier in nuclear reactions, are found to be fed in these decays. A 2675.3 keV (J/sup ..pi../ = 0/sup +/) level seems to be a component of the 2.663 MeV multiplet observed in the (p,t) reaction.
