Abstract
Assuming isospin, the current-current form of the weak interactions of hadrons, and the most general matrix element for the hadron current, expressions are obtained for the decay rate, the final particle energy spectra, and the final baryon-lepton angular correlation. The results are presented in a manner that allows easier comparison between theories and significant data. In particular, a table is given which will allow comparisons between theory and experiment for decay widths. It also allows one to determine which of the many interactions are important in the energy spectra for the various decay modes.
