Abstract : Superconductivity in transition metals, in transition metal alloys, in A-15 compounds and in U6X compounds is studied within the framework of the B.C.S. theory. The electron-phonon coupling constant lambda is expressed in terms of measureable normal-state quantities and an atomic parameter. Then, using the McMillan formula for the superconducting transition temperature Tc, the variation of Tc in the three transition metal series is discussed. Calculated values for Tc are given for several transition metal alloys, U6X compounds and for Sc, Y, Lu, and La. Also, it is shown that in Al5 compounds Cooper pair fluctuations may occur even at temperatures several degrees Kelvin above Tc. (Author)
