Recent Chalk River Experiments on Superallowed $0^{+}\to 0^{+}$ Beta Decays

Abstract

Two experiments, (1) a measurement of the superallowed $0^{+}\to 0^{+}$ branching ratio in ${}^{10}$C, and (2) a measurement of (or limit on) non-analogue $0^{+}\to 0^{+}$ branches in ${}^{38m}$K, ${}^{46}$V, ${}^{50}$Mn and ${}^{54}$Co, are described. The implications these experiments have on the test of the conservation of the weak vector current (CVC) and the unitarity of the Cabibbo-Kobayashi-Maskawa matrix are surveyed.
