Abstract
Inelastic neutron scattering and low-temperature specific heat measurements are reported for a polycrystalline sample of Zr2Fe. Lattice dynamical calc ulation of the phonon spectrum, along with first-principles LMTO electronic structure calculations have been used for deriving the specific heat param eters, the electron-phonon coupling constant and the superconducting transi tion temperature. The results are in fair agreement with the experimental d ata (C) 1999 Elsevier Science B.V. All rights reserved.
