Abstract
We have performed magnetic compression experiments with the two-dimensional gas of hydrogen atoms on liquid at . For 2D phase-space densities higher than 3, the probability of three-body dipole recombination is observed to decrease gradually by an order of magnitude in comparison to its low-density value . This is attributed to local coherence developing in a 2D quasicondensate. We have also determined the value for the mean-field energy of the gas.
