Muon spin relaxation measurements in the layered superconductor NbSe2 have been performed to study the magnetic field penetration depth λ. The relaxation rate σ(T) α λ(T)-2 in field-cooled measurements exhibits a temperature dependence consistent with an isotropic energy gap without anomalous zeros. The low temperature penetration depth λ(T → 0) = 2,500 A ̊ is much larger than that obtained from previous Hc1 measurements.
