Comparison of fusion cross sections for /sup 10/B + /sup 16/O and /sup 12/C + /sup 14/N systems. [Up to 17 MeV/A]

PDF Version Also Available for Download.

Description

The cross sections for fusion are compared for the /sup 10/B + /sup 16/O and /sup 12/C + /sup 14/N systems for bombarding energies up to 17 MeV/A. The energy spectra, angular distributions and relative yields of the evaporation residues are extracted and, by comparison to simple kinematical analysis and Hauser-Feshbach calculations, it is concluded that they are consistent with complete fusion and equilibrium decay. Coincidence measurements for the /sup 14/N + /sup 12/C system at E/sub 14//sub N/ = 182 MeV are also presented and confirm the identification of evaporation residues based on singles measurements of the Z distributions. ... continued below

Description

The cross sections for fusion are compared for the /sup 10/B + /sup 16/O and /sup 12/C + /sup 14/N systems for bombarding energies up to 17 MeV/A. The energy spectra, angular distributions and relative yields of the evaporation residues are extracted and, by comparison to simple kinematical analysis and Hauser-Feshbach calculations, it is concluded that they are consistent with complete fusion and equilibrium decay. Coincidence measurements for the /sup 14/N + /sup 12/C system at E/sub 14//sub N/ = 182 MeV are also presented and confirm the identification of evaporation residues based on singles measurements of the Z distributions. The excitation functions for fusion for the /sup 14/N + /sup 12/C and /sup 10/B + /sup 16/O systems show significant differences that cannot be explained in terms of simple macroscopical models. For the highest energies studied the fusion cross sections decrease as 1/E/sub cm/ for both systems; this result confirms the existence of a maximum absolute angular momentum limit of approx. 27 h-bar. 16 figures.
