Novel Tools for In-beam Proton–gamma Coincidence Spectroscopy Near N=Z
Author
Summary, in English
A novel combination of two CD-shaped double-sided silicon strip
detectors (DSSD) with Gammasphere, Microball, Neutron Shell, and
Fragment Mass Analyzer has been exploited at the Argonne Tandem Linac
Accelerator System (ATLAS) facility at the Argonne National Laboratory
during an experimental campaign aiming to study proton-unbound states in
odd-Z, N<Z nuclei beyond 56Ni. The addition of the highly-pixelated DSSDs to the setup has improved its sensitivity and selectivity for in-beam proton–γ
coincidence spectroscopy. Proton tracking capabilities of the DSSD
system have been utilized for the first time to follow the beam-spot
location on the target, which refines the computation of recoil vectors
and thus proton-line energy resolution. Moreover, the high granularity
of the DSSD system made it sensitive to unambiguously distinguish
evaporated deuterons from evaporated protons. This enables unprecedented
deuteron–γ coincidence studies along the N=Z line.
