摘要: For pt. III, see abstr. A21890 of 1970. A new low-temperature expansion variable for the Ising model is given. Expansions in variable, x=1-tanh(J/kT), then converge right up to critical point. Power series are derived, and analysed by Pade method N-point fits. spontaneous magnetization three dimensions. beta =0.312+or-0.002 simple cubic lattice, =0.3125+or-0.0015 body-centred =0.312+or-0.004 face-centred lattice. susceptibility gamma =1.30+or-0.02, =1.28+or-0.04, '=1.29+or-0.04 cubic, lattices respectively. specific heat authors estimate 1/16
