Recoil Phenomena in Solution

The results in this section are very fragmented, and surprisingly very few systems have been correlated with the radiolytic behaviour of the solvent an exception is the recoil behaviour of 0 in reactor-irradiated water.  

Irradiation of either Sn or Sn in aqueous solution gave large yields of 

and the yield increased as the concentration of Sn in the target increased. Sn gave higher yields of Sn than did Sn, and this was thought to be due to a recoil energy effect. It could also be the result of a radiolysis effect with the solvent. 

The hot-atom chemistry of phosphorus in sulphur and phosphorus compounds, reactor-irradiated in benzene solutions, indicates that a wide range of products is produced. - In one case, greater oxidation of the recoil P is observed in dilute solutions, whereas in the other case thermal reactions of P with carbon atoms dominate for low concentrations but hot reactions seem more important in the higher concentration range. A detailed reaction sequence is given for the phenyl-phosphorus compounds.  

The S resulting from neutron irradiation of LiCl in methanol solution exists in several chemical forms. There is a high yield of S (60%) with S (14%), S +(10%), and S (16%). The presence of water results in S° being converted to S There is some evidence for S being the precursor of S , contrary to the conclusions reached from the work on KQ mentioned earlier.
