摘要：

Visible-UV fluorescence has been analyzed after resonant Cl 2p core excitation of HCl molecules. The dispersed fluorescence spectra are dominated by emissions from atomic fragments. In particular, an intense and polarized Balmer H-alpha line is observed after photoexcitation of the 2p(-1)nl Rydberg states. The excited hydrogen atoms are efficiently produced in the resonant Auger process and the subsequent dissociation of high lying HCl+ states. The experimental results, complemented by a time-resolved measurement of the H-alpha decay, point to a universal mechanism for the production of H(n = 3 ) atoms in the dissociation of innershell excited HCl molecules.
