The interactions between jets of high-energy nuclei and nuclei of the surro
unding medium are studied. Such interactions could be initiated by jets fro
m active galactic nuclei interacting with surrounding cool clouds. The resu
lting nuclear interactions are found to produce copious amounts of H-2 and
He-3 from the He-4 nuclei. These results suggest that jets of particles fro
m quasars could have produced anomalously high abundances in surrounding cl
ouds of some of the nuclides usually thought to characterize big bang nucle
osynthesis, specifically, the H-2 seen in absorption spectra.
