英文摘要	This paper reports the measurement of visible light emission in the collisions of slow (V similar to 0.38 V-Bohr) highly charged Xeq+ (6 <= q <= 23) ions with GaAs surface. The experimental results include Ga I lines from the 4d D-2(3/2) and 5s S-2(1/2) to the 4p P-2(1/2,3/2) states and Ga II lines belonged to the electron transitions 4p(2) D-1(2)-> 4s4p 1P(1), 4s5s S-1(0) -> 4s4p P-1(1) and 4s4f F-1(3) -> 4s4d D-3(3). The measurement on the projectile charge state dependences of Ga II at 270.20, 277.90, 426.20 nm and Ga I at 287.65, 294.55, 403.55, 417.35 nm lines is presented. It is concluded that the photon yields increase with charge state in the same way as the potential energy increases and the potential energy is the driving force for optical emission of excited Ga atoms and Ga+ ions.
