Abstract

It was recently suggested that the odd-even staggering of reaction cross sections is evidence of the pairing anti-halo effect on projectile radii. We define the dimensionless staggering parameters Γrds and ΓR for projectile radii and reaction cross sections, respectively, and analyze the relation between Γrds and ΓR for the scattering of 14,15,16C from a 12C target at 83 MeV/nucleon by taking account of projectile-breakup and nuclear-medium effects with the microscopic version of the continuum discretized coupled-channels method. The value of ΓR deviates from that of Γrds by the projectile-breakup effect, the nuclear-medium effect, and an effect resulting from the fact that the scattering is not exactly black-sphere scattering (BSS). The projectile-breakup and nuclear medium effects nearly cancel for ΓR at low incident energies. The remaining non-BSS effect becomes small as the incident energy decreases, indicating that nucleus-nucleus scattering at lower incident energies can be a good probe for evaluating Γrds from measured reaction cross sections.
