Deformation in the neutron rich sulfur isotopes {sup 40}S and {sup 42}S
- Michigan State Univ., East Lansing, MI (United States); and others
In the experiment described here radioactive beams of {sup 40,42}S and {sup 44,46}Ar (E{approx}40 MeV/nucl.) were produced in the A1200 fragment separator at the National Superconducting Cyclotron Laboratory at Michigan State University by fragmenting an 80 MeV/nucleon {sup 48}Ca{sup 13+} beam in a 379 mg/cm{sup 2} {sup 9}Be target. The exotic ions were positively identified by a time of flight measurement before interacting with the secondary gold target (93.5 mg/cm{sup 2} or 184.1 mg/cm{sup 2}). After interacting with the virtual photon field in the gold target, fragments scattered into a lab angle of less than 4.1{degrees} were detected in a fast/slow plastic phoswich detector located downstream from the secondary target. The energy loss - total energy measurement allowed the rejection of events which led to the breakup of the projectile in the target. Photons from the deexcitation of the projectile were measured in coincidence with beam particles. The photons emitted from the excited projectile can be clearly distinguished from photons coming from the target by their Doppler shift and Doppler broadening.
