Two new photonuclear reactions are reported, he organic retention following the Br/sup 81/( gamma ,n)Br/sup 80m/ reaction in liquid nand isopropyl bromides was found to be 47 snd 36%, respectively, appreciably higher than reported values following the Br/sup 79/(n, gamma )Br/sup 80m/ reaction. Higher retentions were also noted for irradiations of the solid bromides. The relative yields of individual organic products were determined for irradiations of both liquid and solid and were in many respects in striking agreement with data from activation by (n, gamma ) reaction and isomeric transition. In solid n-propyl bromide the ( gamma ,n) and ( gamma ,3n) reactions gave the same ratio of parent compound to total organic yield. Data on the scavenger effect show that thermal recombination reactions occur in both liquid and solid. Marked increases are shown in the thermal organic yield with only slight incresses in the nonthermal retention for both bromides for ( gamma ,n) compared to (n, gamma ) activation. The reasons for these increases are discussed. In general, the data indicate that elastic collision mechanisms are unimportant compared to random fragmentation as an explanation of the results.
