Level Structure and Decay Scheme ofSc43

Abstract

The ${\mathrm{Ca}}^{40}(\alpha ,p){\mathrm{Sc}}^{43}$ and ${\mathrm{Ca}}^{40}(\alpha ,p\gamma ){\mathrm{Sc}}^{43}$ reactions have been used to study the level structure and decay scheme of ${\mathrm{Sc}}^{43}$ from the ground state through 1.95 MeV in excitation. Previously unreported doublets are observed with energies of (1.418, 1.426) and (1.810, 1.826) MeV. There is some indication that a third doublet may lie at (0.846, 0.855) MeV. On the basis of the decay scheme, it is suggested that the levels at 1.810 and 0.475 MeV have spin $\frac{3}{2}$.
