Damaged conditions under irradiation such as ion beams irradiation are transient and unstable. Understanding of this transient damage state is important to clarify the process from damage generation to stabilization. We are developing Age-MOmentum Correlation (AMOC) measurement system by 
-
coincident measurement to investigate the triplet positronium (o-Ps) reactions as a probe of reactive species. From the correlation between "positron annihilation time" and "momentum of electron / positron at pair annihilation" obtained by AMOC measurement, it is possible to investigate the process of o-Ps reactions. We report on AMOC measurement system newly constructed by digital method.

In order to elucidate the transient damage state by ion beam etc., positron annihilation lifetime - momentum correlation (Age-MOmentum Correlation: AMOC) apparatus by - simultaneous measurement is newly constructed by the digital method. In this study, we investigated the effect of -irradiation of polystyrene using the AMOC apparatus. As a result, we obtained that the S parameter near 1 ns decreases corresponding to the increase of damage amount.
