Scrutinizing contaminants via beta spectra and lifetimes in the He6-CRES experiment

We are doing careful analysis searching for possible contaminants that could affect the He6-CRES experiment. The latter

looks at producing high-precision measurements of the beta spectra of 6He and 19Ne. These are produced via

7Li(d,3He) and 19F(p,n). We will present our plan and initial data to search for possible contaminants that could affect

the experiment. The main tools are measurements of halflifes and thick-scintillator data to identify the contaminants.
