用F2分子激光解离7.88 eV(157.5 nm)的HgBr2，结合汞原子从高激发态跃迁产生的荧光，获得了汞团簇Hg2和Hg3的激光诱导荧光。激发过程包括双光子吸收，分子在15.76 eV总光子能量下解离，随后形成金属团簇。
Laser induced fluorescence of the mercury clusters Hg2and Hg3in the spectral range between 300 nm to 510 nm has been obtained from the dissociation of HgBr2at 7.88 eV (157.5 nm) with an F2molecular laser, together with fluorescence from mercury atomic transitions from highly excited states. The excitation process involves two photon absorption which dissociates the molecule at 15.76 eV total photon energy with the subsequent formation of the metallic clusters.
