Transition Probabilities for Low-Lying States inSc46

Lifetimes of the low-lying levels of ${\mathrm{Sc}}^{46}$ have been studied using the ${\mathrm{Sc}}^{45}(d, p\gamma ){\mathrm{Sc}}^{46}$ reaction. The half-life of the 52-keV level was measured to be $t_{\frac{1}{2}}=8.8\mathrm{}\pm 0.4$ μsec, which implies a $B\left(E2\mathrm{}\right)=3.1\mathrm{}\times {10}^{-51\mathrm{}}{e}^2$ ${\mathrm{cm}}^4$ for an $E2\mathrm{}$ transition to the ground state. A comparison of this result with shell-model calculations implies effective charges for the unpaired nucleons of $(e_p+e_n)=5.43e$. Half-life limits from $M1\mathrm{}$ hindrances were observed.
