| Abstract: | Using Anderson model in the non-magnetic limit, we have calculated the jump in specific heat at Tc, (ΔC), for superconducting virtual bound state alloys. It is found that the normalized (ΔC) vs normalized Tc curves deviate considerably from the BCS value. A more significant result of the present study is that the initial slope of such a curve has a maximum value of 3.638. It is the highest value reported in literature for the impurity problem and is much larger than obtained even in a large pair breaking situation like Kondo effect (2.481). |
