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.

Bibliographical note
Funding Information:It should be noted that a systematic investigation of heat capacities of high-quality crystalline samples with different values of T c has not been carried out. It is not incon~ ceivable that crystals witch T c < 17.0 K such as the one reported here could be weak-coupling whereas those with T c > 17.0 K such as that of Ref (5) could be strong coupling. There is evidence of this t)~e of behavior in tunneling experiments on films.\[2\] This work was supported by the DOE under Contract DE-AC02-79ERI0461 and by the NSF under Grant NSF/DMR-806959.
