A New Measurement of the Strength of the Superallowed Fermi Branch in the Beta Decay of $\mathrm{^{10}C}$\ with GAMMASPHERE

ORAL

Abstract

We report a new measurement of the strength of the superallowed \mbox{$\mathrm{0^{+}\rightarrow0^{+}}$} transition in the $\beta$-decay of $\mathrm{^{10}C}$. The experiment was done at the LBNL 88-inch cyclotron using eighty-three GAMMASPHERE germanium detectors. This measurement is similar to an earlier experiment performed at GAMMASPHERE but with a significantly higher statistical precision. Precise knowledge of this branching ratio is necessary to compute the superallowed Fermi \mbox{$\mathit{f}$t-value} which in turn gives the weak vector coupling constant and the u to d element of the Cabibbo-Kobayashi-Maskawa quark mixing matrix.
