Abstract
Transverse-field muon-spin-relaxation () measurements have been performed on () above and below its superconducting transition temperature. The temperature dependence of the magnetic penetration depth, deduced from the data, is that of an ordinary -wave (not -wave with nodes in the gap function) superconductor. The data at 6 K indicate a magnetic penetration depth of Å which, in the limit of extreme anisotropy, reduces to Å.
