TWIST Technote 89

Muon Polarization in the pi+ to mu+ nu gamma decay

(Supplement to TN 82.)

Pierre Depommier, 11 January 2004

This technote 89 is a supplement to technote 82. It contains additional graphs. The conclusion is that the radiative pion decay has a negligible influence on the muon polarization in the conditions of the TWIST experiment.
