The gamma-ray spectra for the decays K yields mu v gamma and K yields ev gamma as well as pi yields mu v gamma and pi yields ev gamma are calculated in full: Terms in the spectra proportional to lepton mass are retained so that the results are applicable to the muon decay mode, and the calculations take into account both inner Bremsstrahlung radiation and radiation arising from structure in the meson vertex. The latter contributions are expressed in terms of two form factors. The modes K yields mu v gamma and K yields ev gamma can be used to test the validity of Wigner timereversal invariance. Two ways of doing this are given, one based on measurements of the gamma spectra and the other on measurements of the transverse polarization of the muons from the K yields mu v gamma decay. Calculations were carried out on the effect of a possible intermediate vector boson on the decay K yields ev gamma . Contributions from internal Bremsstrah lung radiation are given. The strongly interacting intermediate states which give rise to structure-dependent radiation are listed, and a discussion of possible ambiguities, arising from these states, is given. (auth)
