The specific heat of A-15 Mo0.4Tc0.6 has been, measured in a 7-T magnetic field in order to suppress the superconducting transition. With normal state data now available from 7 to 25 K, an improved determination over previous work of λ and 2δ/kT c was possible. Thus, more accurate values for λ (6.2±0.5mJ/g-atom K2) and 2δ/kT c (5.3±0.5) have been determined. These parameters present a more believable picture of the strong coupling behavior of A-15 Mo0.4Tc0.6 than previously presented. In addition, the low-temperature specific heat data were extended to 1.4 K from the previous work's low of 4 K. These new data enable a determination of θD at T = 0 (349±5 K) and θD at 7 K (306±5 K) versus the high-temperature θD at T = 13 K previously determined (271±3 K).
