The control production of antihydrogen (H̄) was demonstrated using laser-controlled exchange method. The atoms showed by essentially back-ground-free detection were a small fraction, because of small detection solid angle and number of trials. It was observed that the produced antihydrogen had the velocity distribution of the p̄ from which they form. The results show that the laser-controlled charge exchange method could become the method of choice for producing cold antihydrogen to be trapped for spectroscopic comparisons with hydrogen to test fundamental symmetries.
