For proton-rich nuclei, charged particle emission competes with beta decay and electron capture. One notable region of this competition is the nuclei northeast of 100Sn, where alpha-decay becomes prominent, and the proton drip line competes with proton emitters; see the cases of as 109I and 108I [1,2]. With decreasing half-lives close to the drip line, scintillators become optimal for measuring sequential decay signals [3,4]. This work will discuss the methods of identifying pileup in scintillator signals, techniques for separating pileup signals, the current limitations of fast decay measurements, and correction techniques for scintillators implemented to measure charged particles. Specifically, this work will discuss the alpha-decaying nuclei near 100Sn, such as the decay chain of 109Xe along with the individual decays of 105Te and 108I from a recent experiment at RIBF RIKEN. The advantages and drawbacks of using scintillators to measure these nuclei will be discussed.
