Abstract
The factors for the capture process of the systems +, +, +, +, +, +, and + are calculated at sub-Coulomb barrier energies in a model using an inverted parabola which joins smoothly onto the Coulomb potential between two heavy ions. The model does not have any discontinuous potential surface and has proper asymptotic forms for the wave functions and has been successful in understanding fusion cross sections at higher energies. The calculated energy dependence of the factor follows in general the experimental trend and in many instances, the observed magnitudes can be reproduced remarkably well.
