| Abstract: | Abstract We study the different spin - states of Sz = 0, 1/2, 1,3/2,2, 5/2,… of different ultrasmall metallic grains which observe the rules in Gauss orthogonal ensemble by the theory of statistic ensembles, and find there exist critical level spacings dc/△ (0) = 13.81,1.85,0.81,0.50, 0. 36, 0. 28, … , at which the superconductivity would vanish. We also find that the higher the spin - state, the smaller the critical level spacing, and for the state of Sz = 0 there actually exists the superconducting enhancement. |
