Abstract
The in-plane magnetic field penetration depth lambda(ab) of the organic sup erconductor kappa-(BEDT-TTF)(2)Cu[N(CN)(2)]Br has been derived from the tem perature dependence of the H-1 NMR line shape : lambda(ab)(T = 0) = 4920 +/ - 100 Angstrom. Its linear low temperature behavior is consistent with an a nisotropic superconducting gap with lines of nodes.
