Abstract 



Electron continement and its effect on the superconductingtonormal phase transition driven by a magentic field and/or a current is studied in nanowires. Our investigation is based on a selfconsistent numerical solution of the Bogoliubovde Gennes equations. We find that in a parallel magneitc field and/or in the presence of a supercurrent the transition from the superconducting to the normal phase occurs as a cascade of discontinuous jumps in the superconducting order parameter for diameters D < 10 divided by 15 nm at T = 0. The critical magentic field exhibits quantumsize oscillations with pronounced resonant enhancements as a function of the wire radius.
