中文摘要：

利用国家同步辐射实验室合肥光源的真空紫外同步辐射,使NO分子和Ar原子混合物的超声分子束发生光电离,测量了Ar,NO和异类团簇Ar·NO的光电离效率谱.在谱中,在与Ar原子的共振线对应的能量区域（11.5-12.0eV）观察到一个强的类共振结构.这个结果表明,在异类团簇Ar·NO的内部,稀有气体Ar原子的激发能转移到与它接触的分子NO上,使分子NO发生电离.

英文摘要：

A supersonic beam of NO molecules mixed with Ar atoms was ionized by VUV synchrotron radiation from Hefei Light Source （HLS） at National Synchrotron Radiation Laboratory （NSRL）. Photoionization efficiency spectroscopy （PIES） measurement was made for NO, Ar and heterogeneous dusters Ar·NO. In PIES spectum of Ar·NO, a strong resonance peak at the position of atomic rare gas resonance lines （11.5-12.0 eV） was observed, and it is shown that the excitation energy of the rare gas atom is transferred to the attached NO molecule within a heterogeneous cluster, leading to ionization of the molecule NO.
