Structure of43Scin theα+39Kcluster model

Abstract

The structure of ${}^{43}\mathrm{Sc}$ is investigated by the $\ensuremath{\alpha}{+}^{39}\mathrm{K}$ orthogonality condition model. The properties investigated are energy spectra, $\ensuremath{\alpha}$-spectroscopic factors, $E2$, $M1$, and $E1$ transitions. On the whole, the calculated properties are in good agreement with the available experimental data. Low-lying levels are assigned to the weak coupling multiplets based on $\ensuremath{\alpha}{+}^{39}\mathrm{K}{(3/2}^{+})$ and $\ensuremath{\alpha}{+}^{39}\mathrm{K}{(1/2}^{+})$ cluster configurations and interesting selectivities for $M1$ and $E1$ transitions are discussed.
