One Proton Knockout from $^{83}$As

POSTER

Abstract

We present a one-proton knockout measurement from the $N=50$ nucleus $^{83}$As, conducted at the National Superconducting Cyclotron Laboratory at Michigan State University (NSCL). A cocktail beam composed primarily of $^{82}$Ge (56\%) and $^{83}$As (35\%) was produced through fragmentation of a $^{86}$Kr beam incident on a $^9$Be primary target. Incoming beam particles are identified by time of flight, and reaction products are identified with the S800 Magnetic Spectrograph. Gamma rays from the beam-like reaction products were captured by the Segmented Germanium Array (SeGA). Preliminary results will be discussed.
