Abstract
A method is developed for calculating microscopic form factors for two-nucleon transfer reactions between heavy ions in the distorted-wave Born approximation. This method utilizes a multipole expansion of the two-nucleon overlap integrals in terms of the relative angular momentum of a transferred nucleon pair, which is found to converge very rapidly. Sample calculations are carried out for the reaction (, ) at MeV, leading to the ground and excited states. The calculations underpredict the experimental cross sections by a factor of about 10 for the , , and state transitions. It is also found that the singlet () and triplet () two-nucleon transfers contribute about equally to the cross section.
