摘要：

A dispersion curve for Rayleigh-Taylor growth rates in the linear regime has been measured in planar CH2 laser-driven foils. The foils were ablatively accelerated with a single, smoothed, frequency-doubled beam of the Nova laser at 7 x 10(13) W/cm(2) (giving an acceleration of 60 mu m/ns(2)). Measured growth rates were about 50% of the classical values. Growth rates simulated with the computer code LASNEX were similar to 18% higher than measured values.
