Neutron-pair transfer formalism including deformation in gauge space for target and projectile

We propose a macroscopic description of multiple neutron-pair transfer in heavy-ion reactions which takes into account explicitly the nuclear deformations in gauge space of the target and projectile. The requirement of conservation of the total number of particles yields an interaction potential that depends only on a single variable. The intrinsic coordinate-dependent phase-shift formalism is then used to evaluate cross sections. (orig.)
