Influence of radiation-induced species on positronium formation in poly(methylmethacrylate) at low temperature
Creators
Description
Impurity effect, elapsed time dependence, visible light bleaching effect, and temperature dependence on positronium formation probabilities were measured at temperatures ranging from 25 to 300 K for poly(methylmethacrylate) (PMMA). In order to clarify the radiation-induced species, IR-UV absorption spectra were obtained as a function of temperature for PMMA irradiated at 77 K. PMMA anion radical was stable at low temperatures. It is suggested that PMMA anion radical and both MMA monomer and dimmer anion radicals strongly contribute to Ps formation at low temperatures
