A Possible Alternative to the R-Process
Abstract
It is shown that it is possible to produce those nuclei commonly attributed to the r-process in a process wherein n,y reactions compete with -decay, as opposed to the r-process in which a n, ,n equilibrium exists and the beta rates are much slower. This neutron-capture fl-decay competition process (called the n-process) can reproduce solar-system r-process abundances under conditions very different and less extreme from those required for an r-process. In particular some current nova and supernova shock models may qualify. Thus it might be easier to find an astrophysical site for the n-process than for the r-process.
