We study superconducting correlations in small metallic dot with fixed particle number in an applied magnetic field. We determine the tunneling spectra finding a good qualitative agreement with experimental data. For utrasmall dots we report an example of ``softening{''} of the crossover by a ``superconductive{''} state to a normal one due to the magnetic field.

Abstract
We study superconducting correlations in small metallic dot with fixed particle number in an applied magnetic field. We determine the tunneling spectra finding a good qualitative agreement with experimental data. For utrasmall dots we report an example of ``softening{''} of the crossover by a ``superconductive{''} state to a normal one due to the magnetic field.File in questo prodotto:
