The hydrogen chemisorption on the surface is monitored by the surface photoabsorption method with a halogen transport ALE growth system. The AH, enthalpy change according to the hydrogen chemisorption, obtained by the in situ monitoring is +81.7 kJ/mol. The total energy change calculated by ab initio method is closed to the experimental results. The purpose of the present work is to monitor the hydrogen chemisorption on the (111)A Ga surface under an atmospheric pressure and to determine the atomic configuration on the surface by ab initio calculation.
