Abstract: | A two-humped model was proposed for explaining the suppression of the cross sections for the deep-subbarrier fusion of spherical
nuclei that have intermediate atomic numbers. It was shown that the suppression of these cross sections was due to the interference
between the incident and reflected fluxes between the two barriers. The results of fitting the cross sections calculated within
the two-humped model revealed the invariability of the distance between the vertices of the two barriers. As the charges of
colliding nuclei increase, the inner barrier becomes higher than the outer one, and this determines the competition with cross
sections for deep-inelastic-transfer reactions. |
