Abstract
The dissociation of excited state Br2 is probed with the novel technique of ultrafast soft x-ray photoelectron spectroscopy. Excited Br2 molecules are prepared in the dissociative 1IIu state with 80 fs 400 nm pulses, and a series of photoelectron spectra are obtained during dissociation with pulses of soft x-ray light (47 nm, 26.4 eV, 250 fs). The formation of Br atoms is readily detected and the data support a dissociation time for Br2 on the order of 40 fs. Amplitudes of the pump-probe features reveal that the ionization cross-section of atomic Br at 47 nm is nearly equal to} 40 times larger than that of Br2.Citation
