用两组能量围绕Ｐ和ＩｎＫ壳层结合能上下的同步辐射单色Ｘ光对ＩｎＰ单晶［１００］表面进行辐照。结果表明，无论Ｘ光子被Ｐ原子Ｋ壳层吸收还是被Ｉｎ原子Ｋ壳层吸收，ＩｎＰ单晶［１００］表面Ｐ原子芯能级２Ｐ电子态变化明显。Ｐ和Ｉｎ原子Ｋ壳层Ｘ光吸收对ＩｎＰ单晶表面辐射损伤增强因子分别为４．４ｘ１０－６ｋｇ／Ｃ和３．１ｘ１０－５ｋｇ／Ｃ InP single crystal [100] surfaces are irradiated with two sets of energy around the P and InK shells in combination with synchrotron radiation monochromatic X-rays. The results show that the 2P electronic states of P atoms on the InP single crystal surface [100] are obviously changed regardless of whether the X-photons are absorbed by the K shell of the P atom or absorbed by the K shell of the In atom. The enhancement factors of X-ray absorption of P and In K shells on the surface of InP single crystal were 4.4 × 10-6kg / C and 3.1 × 10-5kg / C
