Magnetic properties of the nucleus~lectron complex system which has the electronic singlet ground state are reanalyaed numerically in the vicinity of the threshold D/2J= I , D being the energy splitting between the electronic ground and excited states. The spontaneous polarization of the electron spin increases steeply far below T. by the effect of the nuclear spin. A fair agreement with the neutron diffraction experiment can be obtained for the praseodymium metal if it is assumed that the praseodymium metal is slightly in the nuclear regime, D/2J= 1 .O002. In such case the nuclear specific heat is expected to show the narrowed Schottky type.
