Proton Pandemonium: A first look at the $^{31}$Cl($βp γ$)$^{30}$P decay scheme

Positron decays of proton-rich nuclides exhibit large $Q$ values, producing complex cascades which often involve various radiations, including protons and $γ$ rays. Often, only one of the two are measured in a single experiment, limiting the accuracy and completeness of the decay scheme. An example is $^{31}$Cl, for which protons and $γ$ rays have been measured in detail individually but never with substantial sensitivity to proton-$γ$ …
