In vacuo, during an interaction between a moving atom and a surface wave of frequencyv, the exchanged momentum is greater thanhv/c. First we show, using a semi-classical treatment, that this momentum is ħkxin agreement with De Broglie's relationp= ħk, but unlike the usual notion of wave momentum attached to the Poynting vector. We present experimental methods to measure this momentum and we give results for two atom speeds.
