Abstract
A linearized form for the screened form factors of electron-phonon int eraction in the metallic glass Mg70Zn30 is applied for the first time to predict the superconducting state parameters viz. electron-phonon c oupling strength (lambda), Coulomb pseudopotential (mu), transition t emperature (T-c), isotope effect exponent (alpha) and the interaction strength (N-0 V). Computed results agree with the experimental data av ailable in the literature.
