Abstract

The rate constant for the quenching of positronium by nitromethane was found to depend very strongly on the solvent (k_H20åk_benzene). This together with the data on surface tension leads to the rejection of the "internal pressure effect" of Kobayashi and Ujihara. The higher quenching rate constant in the case of water is explained as due to a stronger bond between H₂0 and nitromethane than between benzene and nitromethane.
