Abstract
A new systematic shift of the single-particle spectra of nuclei under the Coulomb interaction is considered. This shift results from the interplay between the Coulomb interaction and strong interaction, being greatly enhanced by the presence of the nuclear surface. This shift affects the position of the calculated proton drip line decreasing the maximal Z of a nucleus near the drip line by several units. The same mechanism is responsible for significant corrections to the mass difference of the mirror nuclei and to the effective proton mass.
