On Volatility, First Ionization Potential, and s- and r- Processes
Abstract
The possibility of a correlation between the first ionization potential and volatility (in that elements of low potential tend to be refractory and those of high potential volatile) is considered. It is noted that the apparent correlation between galactic cosmic ray source (GCRS) elemental abundances and the first ionization potential may in fact be based on volatility. Attention is given here to compositional clues which may determine whether volatility or the first ionization potential is the relevant parameter. The correlation between the first ionization potential and volatility is examined, and those elements which do not fit into the correlation are isolated. Attention is also given to possible ambiguities in interpreting the charge spectrum beyond Ni that derive from coincidences between regions of change in the first ionization (and volatility) and the s- and r-process peaks.
