Abstract

We have produced beams of light neutron rich nuclei (Z<20) in the A1200 fragment separator at the NSCL by fragmenting high intensity 48Ca beams (E=70 and 80 MeV/nucl.) in a 379 mg/cm2 beryllium target. The exotic beams then impinged on a secondary gold target where they were excited in the Coulomb field of the target. The nuclei de-excite from a bound state by emission of a discrete photon, thus establishing the existence and energy of this state. Using a high efficiency position sensitive photon spectrometer we were able to detect photons from eight even-even nuclei far from the valley of stability (44,46Ar, 40,42,44S, 34,36,38Si) and to correct for the considerable Doppler shifts and Doppler broadening of the photo peaks.
