Abstract

The specific heat of a transforming V3Si crystal with a superconducting transition temperature of 16.8 K has been measured as a function of temperature over the range from 30 K to 2.6 K. The electronic specific heat in the superconducting state is found to be that of a weak-coupling BCS superconductor characterized by 2Δ(0)kBTc = 3.46. This result follows from an analysis in which the lattice specific heat below the structural transition temperature is treated using a simple Debye model.
