Structure and superconducting properties of low-vacuum aluminum condensates

We report the first studies of the superconducting properties of low-vacuum aluminum condensates (LVAC). We have determined the critical temperatures T/sub c/, the width of the transition to the superconducting state ..delta..T, and the temperature dependence of the critical field near T/sub c/. We have established the dependence of T/sub c/ on the electron mean free path length l/sub eff/ and demonstrate a relationship between l/sub eff/ and the condensation conditions.
