The probability of pion capture by hydrogen was measured for CH3OH, CD3OH, and CH3OD as a function of temperature from -150 to +250°C. The nuclear capture of a pion by a proton was identified using the pion charge-exchange reaction. The coincident photons from the 0 decay were detected by TRIUMFs large NaI spectrometers. We have found a relative difference of 1.79±0.11 in the pion capture probability in solid and supercritical CD3OH that is interpreted in terms of the hydrogen-bond-breaking model.
