Abstract : Measurements have been made of the critical-field curve, H sub c versus T, for eight superconducting dilute alloys of indium in tin near the critical temperature and at low temperatures extending to 0.3 K. The effective magnitude of the superconducting energy gap is sensitive to the direction of the electron momentum relative to the crystal lattice - the so-called anisotropy effect. The reduction in electron mean free path which occurs upon addition of indium to pure tin reduces the effect of anisotropy in the electron-electron interaction.
