Femtosecond spectroscopy of molecular autoionization and fragmentation
(1990)
Femtosecond laser pulses are applied to the study of the dynamics and the pathways of multiphoton-induced ionization, autoionization, and fragmentation of Na_2 in molecular-beam experiments. In particular,
we report on first results obtained studying electronic autoionization (leading to Na_2{^+} + {e ^-}) and
autoionization-induced fragmentation (leading to Na{^+} + Na + {e ^-}) of a bound doubly excited molecular state. The final continuum states are analyzed by photoelectron spectroscopy and by measuring the ...
