Abstract
The fractions Theta(beta) and Theta(X) of spin-correlated singlet radi cal-ion pairs in alkane solutions irradiated by P-particles and X-rays were got from experiments on magnetic held effect and quantum beats i n recombination fluorescence. The ratio Theta(beta)/Theta(X) values of 1.3-2.8 for the solvent series studied were found both from magnetic effect and quantum beats. The Monte Carlo calculations were made to ex plain the variations of Theta(beta)/Theta(X) in different solvents. Th e high value of Theta(beta)/Theta(X) = 2.8 for isooctane is probably d ue both to large separation between ions in pair and to high concentra tion of neutral radical in the spur.
