COMPARISON OF THE LINEAR-ENERGY-TRANSFER EFFECT IN THE RADIOLYSIS OF CYCLOPENTANE, CYCLOHEXANE AND CYCLOOCTANE

In the radioanalysis of cyclopentane, cyclhexane and cyclooctane, chan ging the irradiating particles from the gamma-rays to heavy ions, ther e are indications for the increase of the proportion of the H atom for ming reaction at the expense of the reactions leading to H-2 molecule elimination and to radical production without participation of H atoms . This shift is attributed to changes in charge recombination with the increasing LET from basically geminate recombination to predominantly cross combination. The iodine scavenging results are similar in the t hree systems which is attributed to the basically diffusion controlled character of the competing reactions.
