The R-matrix description can be extended to the unresolved resonance region, where average resonance parameters can be adjusted to describe the cross sections. ...

P-nuclei
p-Nuclei (p stands for proton-rich) are certain proton-rich, naturally occurring isotopes of some elements between selenium and mercury which cannot be produced in either s- or r-process.
