Abstract

The temperature dependence of the electrical resistance R(T) and the upper critical field H//c//2(T) have been measured. The value of the electron-phonon interaction parameter lambda was estimated based on the nearly free electron model and the strong coupling theory of superconductivity. After an analysis based on the nearly free electron model and the BCS theory, some other parameters such as the mean free path l, the Fermi velocity v//F, the coherence length xi //o, the London penetration depth lambda //L(0), and the GL parameter k, were also estimated.
