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 clusters 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.
