N=85nuclei. I. Decay ofPr145to levels ofNd145

A $\gamma$-ray spectroscopy study of the decay of ${}_{}{}^{145}{}_{}{}^{}\mathrm{Pr}$ has led to the identification of 61 $\gamma$ rays. These and $\gamma -\gamma$ coincidence studies have been used to identify 20 levels in ${}_{}{}^{145}{}_{}{}^{}\mathrm{Nd}$ at ($J^{\pi }$ value in parentheses): ground state (${\frac{7}{2}}^{-}$), $67.1 \left({\frac{3}{2}}^{-}\right)$, $72.50 \left({\frac{5}{2}}^{-}\right)$, $657.67 \left({\frac{11}{2}}^{-}\right)$, $748.28 \left({\frac{9}{2}}^{-}\right)$, $780.45 \left({\frac{3}{2}}^{-}\right)$, $919.9 \left({\frac{1}{2}}^{-}\right)$, $920.72 \left({\frac{9}{2}}^{-}\right)$, $937.05 \left({\frac{5}{2}}^{-}\right)$, $1011.22 \left({\frac{11}{2}}^{-}\right)$, $1051.41 \left({\frac{7}{2}}^{-}\right)$, $1085.2 \left({\frac{3}{2}}^{+}\right)$, $1150.26 \left({\frac{9}{2}}^{\pm }\right)$, $1101.05 \left({\frac{5}{2}}^{-}\right)$, $1161.05 \left({\frac{5}{2}}^{-}\right)$, 1162.32 (-), $1249.7 \left({\frac{5}{2}}^{-}\right)$ 1285.6 (-), 1338.6 (-), $1403.92 \left({\frac{5}{2}}^{-}\right)$, and $1527.05 \left({\frac{9}{2}}^{-}\right)$ keV. These levels and these properties are discussed in terms of the clustering and the dressed $n$-quasiparticle model.
