Using CHIMERA detector at LNS for gamma-particle coincidences

We have recently evaluated the quality of γ -ray angular distributions that can be extracted in particle-gamma coincidence measurements using the CHIMERA detector at LNS. γ -rays have been detected using the CsI(Tl) detectors of the spherical part of the CHIMERA array. Very clean γ -rays angular distributions were extracted in reactions induced by different stable beams impinging on 12 C thin targets. The results evidenced an effect of projectile spin flip on the γ -rays angular distributions. γ -particle coincidence measurements were also performed in reactions induced by neutron rich exotic beams produced through in-flight fragmentation at LNS. In recent experiments also the Farcos array was used to improve energy and angular resolution measurements of the detected charged particles. Results obtained with both stable and radioactive beams are reported.
