title: Application of minimal subtraction renormalization to crossover behavior near the 3He liquid-vapor critical point.
abstract: Parametric expressions are used to calculate the isothermal susceptibility, specific heat, order parameter, and correlation length along the critical isochore and coexistence curve from the asymptotic region to crossover region. These expressions are based on the minimal-subtraction renormalization scheme within the phi(4) model. Using two adjustable parameters in these expressions, we fit the theory globally to recently obtained experimental measurements of isothermal susceptibility and specific heat along the critical isochore and coexistence curve, and early measurements of coexistence curve and light scattering intensity along the critical isochore of 3He near its liquid-vapor critical point. The theory provides good agreement with these experimental measurements within the reduced temperature range |t|<or=2x10(-2).
