We report on photon emissions in the 200 800nm region resulting from collisions of 200keV protons with H2O . The most prominent features observed in the spectrum are the Balmer series of hydrogen and two OH molecular bands. Several less intense O+ as well as neutral O lines are also observed. The absolute photon emission cross sections of the major lines and bands were measured. The results indicate that a primary dissociation pathway involves the formation of H2O+ by removing a 1b2 electron. The unstable H2O+ ion further dissociates into H++OH or OH++H . The dominant presence of neutral hydrogen lines and O+ lines leads to the conclusion that the subsequent dissociation of OH+ into H+O+ prevails over the other possible dissociation pathway leading to H+ and neutral oxygen fragments.
