Deep inelastic collisions and fusion of 20Ne with 40Ca at 151 MeV

Fusion and elastic scattering angular distributions were measured with natural Ca target, 100 μg/cm2 thick, and bombarded by 20Ne(6+) beams at 151 MeV from the Grenoble isochronous cyclotron. The evaporation residues from the compound nucleus were detected by a gas-flow ionization chamber (ΔE) containing a surface-barrier Si detector (E) on the rear side. The evaporation products belong to a peak in the E vs. ΔE plane with a ridge running toward ΔE=E=0. The fusion angular distributions were measured by comparison with the elastic events and a monitor detector placed at a fixed angle. The elastic angular distributions were simultaneously measured on the opposite side of the beam direction by means of three Si detectors. (author)
