    “…Combining this result with previous data leads to the value (98.28+or-0.06)% for the branching ratio of the ground state (superallowed) transitions. This does not resolve the apparent anomalousness of the derived Cabibbo angle for this transition, which now stands at theta /sub v/<0.10 with a 95% confidence level. (31 refs).…”
