GEANT4 simulations for use with DSAM targets

The role of 3N forces in the structure of the lightest nuclei is an open question in nuclear physics. Studying electromagnetic transition strengths in key light nuclei enables better understanding and quantification of 3N forces’ significance. While many of the key electromagnetic transition strengths in light nuclei are considered to be "known,” many are decades old with large error bars. This often makes such electromagnetic transition strengths unable to distinguish between different theoretical approaches, which vary in how significant a role the 3N force plays in the nuclear potential. Our efforts aim to improve these transition rate measurements using precision DSAM. However, accuracy in DSAM is intimately tied to one’s understanding of target composition. With this in mind, a local program at UML is underway to produce and characterize targets needed to perform precision DSAM. The target production method implants deuterons and alphas ions at a controllable depth with a controllable dose in heavy Z foils. This work will highlight the creation and use of customized GEANT4 simulations in the planning and validation of precision ion implanted foils.
