Sažetak
We have used the PIBETA detector at the PSI for a precise measurement of rare pion and muon weak decays. We have collected a large statistic al sample of (1) pi+->e+ni_e, (2) pi+->pi0e+ni_e, (3) pi+->e+ni_egama, (4) pi+->e+ni_eni_mi, and (5) pi+->e+ni_eni_migama decays. We have evaluated the aboslute branching ratiosfor these processes by normalizing to the independently measured number of decaying pi+'s (or pi+'s). We discuss the mutual consistency of the preliminary results.
