Abstract
The structure of ¹⁵²Nd, produced via $\beta^{-}$ decay of ¹⁵²Pr, has been investigated using $\gamma$ - $\gamma$ coincidence, $\gamma$ - $\gamma$ angular correlation, and $\beta$ - $\gamma$ - $\gamma$ triple coincidence measurements. Praseodymium activities were obtained by the thermal neutron fission of ²³⁵U and collected by the on-line isotope separator KUR-ISOL. Nineteen $\gamma$ -rays and four excited states were newly found. The spins of six exited states were determined and the parities of three of them were also deduced. The spin and parity of the ¹⁵²Pr ground state, which were previously considered as 4^-, are proposed to be 4⁺ by the present study.
