The Rayleigh-Taylor evolution of 3D broadband perturbations seeded by 351-nm laser nonuniformities was measured in accelerated planar targets using x-ray radiography at {approximately}1.3 keV . Fourier analysis shows that the pertubations evolve to longer wavelengths with shorter wavelengths saturating. The saturation amplitudes and rates of growth of 3D features are consistent with the predictions of Haan [Phys.thinspthinspRev.thinspthinspA {bold 39}, 5812 (1989)]. {copyright} {ital 1998} {ital The American Physical Society}
