We present the first experimental results of quenching (ionization) of H(n/sub 0/ = 43--49) atoms by a linearly polarized microwave electric field consisting of two frequencies (7.58 and 11.89 GHz). Adding a second frequency increases the quenching probability over that for only one frequency, especially where there is local stability at scaled frequencies near certain rational fractions, e.g., n/sub 0//sup 3/..omega.. = (1/6 and (1/5. Some, but not all, two-frequency quench curves display a rich structure that appears to be related to that observed in some single-frequency quench curves.
