Isotope effect in superconducting gallium
Abstract
The superconducting transitions of 69Ga, natural Ga, and 71Ga have been measured. The transition temperatures Tc were found to be 1.0897 ± 0.0003, 1.0845 ± 0.0003 and 1.0770 ± 0.0003 respectively, giving z = 0.41 ± 0.02 and ζ = 0.17 ± 0.04 as parameters in Tc ∞ M- z = M-0.5(1- ζ) .
