Light Particle Coincidences with Gross Structure in Energy Spectra from the exp 40 Ca+ exp 40 Ca Collision

摘要

Angular correlations between light charged particles and heavy ion fragments from the exp 40 Ca + exp 40 Ca collision have been investigated. The high excitation energy structure previously observed in inclusive experiments is strongly populated in coincidence with protons for calcium and potassium fragments, with alphas for argon fragments. Particles emitted in coincidence with the structure are strongly focused and have a velocity close to the velocity of the beam, whereas the yield of evaporation decay is very small.
