A(+) A-, ALPHA, NU, AND FS-XI(3) FROM 3D ISING ENERGY AND SPECIFIC-HEAT/

We analyse Monte Carlo data for the energy and specific heat at and cl ose to the critical point of the 3D cubic Ising model. From the finite -size scaling of the energy E and the specific heat C at criticality w e obtain the estimate v = 0.6308(10). Furthermore, one obtains precise estimates for the 'backgrounds' (nonsingular parts) E-ns and C-ns. Fi tting solely off-critical energy estimates to a scaling law, we find, depending on the choice of the reduced temperature, either A(+)/A(-) = 0.550(12) and alpha = 0.1115(37), or A(+)/A(-) = 0.567(16) and alpha = 0.1047(48). Including information from the data at T-c, we obtain th e estimate A(+)/A(-) = 0.560(10). We also determine the universal comb ination f(s)xi(3) in both phases.
