 note = {application/pdf, 紀要論文, The grand partition function specified by the total particle number, the z-component of the total angular momentum and the total energy of a fermion system composed of particles moving independently in a central potential field is set up and evaluated approximately for a parabolic potential field. The distribution of the number of levels with respect to the z-component of the total angular momentum is found to be Gaussian with the dispersion roughly proportional to the four thirds power of the total number.},
