Abstract
The pairing gap obtained adding the bare nucleon-nucleon potential and the interaction induced from the exchange of collective vibrations is strongly peaked at the nuclear surface. It is possible to mock up the detailed spatial dependence of this field using a contact interaction, with parameters which are quite different from those commonly used in more phenomenological approaches.
