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.
