Nuclear reaction measurements of 80.5 MeV/u [formula omitted]C beam bombarding on C, Cu, W, Au, Pb targets

Abstract

To get the energy distributions and cross sections of emitted light charged particles, and to explore the nuclear reaction, experiments of 80.5 MeV/u 12C beam bombarding on C, Cu, W, Au, Pb targets have been carried out at Institute of Modern Physics, Chinese Academy of Sciences. 30°, 60°, and 120° relative to the incident beam have been detected using three sets of telescope detectors. The method of ΔE−ΔE−E was used for particle identification. Results indicate that heavier targets have larger double differential cross sections, and the emitted fragments tend to go forward. Besides, the decrease of cross sections of fragments produced with the increasing emitted angles follows a kind of pattern.
