Reactions of /sup 20/Ne with /sup 12/C

Journal Article · · Phys. Rev. C; (United States)
;

All reaction products with Z> or =5 emitted from the bombardment of /sup 12/C by /sup 20/Ne beams with incident energies between 54 and 80 MeV have been measured over a wide range of exit energies and angles. The quasielastic, strongly damped, and complete fusion processes were studied. At forward angles both the elastic and inelastic data show the effect of strong volume absorption. At larger angles the paucity in open direct channels manifests itself by a resonantlike behavior of the excitation functions for all outgoing channels reminiscent to that observed for /sup 16/O+/sup 16/O. The energy dependence of the cross section for complete fusion also shows structure, but the average magnitude of the /sup 20/Ne+/sup 12/C fusion cross section is 1100 mb compared to 900 mb for /sup 16/O+/sup 16/O. At backward angles the /sup 20/Ne+/sup 12/C quasielastic angular distribution and excitation functions show the same characteristics seen in heavier systems (e.g., /sup 28/Si+/sup 12/C). However, a much larger yield exists for transitions to high excitation energies (large negative Q values). This strongly damped process has a large cross section and shows all the characteristics of a long lived orbiting /sup 20/Ne+/sup 12/C dinuclear system.
