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