Nd144levels fed inβdecay ofPr144isomers

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