Abstract
The fragmentation of organic molecules by positrons of energy below th e threshold for formation of free-space positronium, named positrolysi s, is compared with pyrolysis and photolysis. The fragmentation patter n is predicted for acetone to yield the CH3CO+ ion, with possibly some CH3+, the reason being that these result from the lowest-energy proce sses. In the other cases considered, the theory is qualitatively consi stent with published experimental fragmentation patterns.
