N2 - A consistent picture of conventional superconductivity in UPt3 is presented which explains qualitatively the gap anisotropy, the dependence of Tc on crystal perfection, the low value of the specific heat discontinuity at Tc and the induced magnetic form factor. The model obtained is based on results of a local density band calculation for UPt3 which are in excellent agreement with photoemission experiments and on estimates of the strength and anisotropy of the electron-phonon interaction. The key feature is anisotropy of the superconducting energy gap which arises from the variation of the electronic mass on the Fermi surface.
