Abstract
The heat capacities, transition temperatures, electrical resistivities, and upper critical fields have been measured for a series of La/sub 1-x/Ga/sub x/ alloys with x = 0.16--x = 0.28. Values of the Debye temperature, density of states, and electron-phonon coupling constant have been determined from these measurements. Superconductivity in this amorphous system is of the intermediate-coupling nature with lambda approx. = 0.8 and the ratio of the nonphonon-renormalized density of states to that of the free-electron model is N/sub ..gamma../(0)/(1 + lambda) N/sub FE/ approx. = 2.2. Specific-heat data as a function of concentration suggest a change in short-range order for x between 0.22 and 0.26.
