We have designed and constructed a negative ion threshold photodetachment spectrometer with 3 cm-' (0.37 meV) resolution. Threshold photodetachment spectra of I-and SH-have been obtained. For SH-. individual rotational transitions between the ion and neutral appear as clearly resolved peaks. ' NSER

โฆ Synopsis
A crossed beam esperiment usmg n surFace ionization negative ion :;ource and a xenon arc lamp has allowed the relative cross seciion tiu photodetachment of an electron from a negative ion of tetracyanoelhylene to be determined for photons in the energy rang 2.1--3.5 cV (590-350 nm). Tha threshold energy was found to be 2.03 + O.G7 ev.

The dynamics following two-photon excitation of an aqueous halide ion are studied via quantum simulation. Two channels for photodetachment are observed: a direct detachment via a very early time non-adiabatic transition and a delayed adiabatic detachment from the lowest-lying charge-transfer-to-solv
A model for the fullerene anion Cg-o is proposed in which the outer electron moves in an attractive deltafunction potential in the shape of a spherical bubble. Exact solutions for this "Dirac bubble potential" were previously worked out. On the basis of this model, the photodetachment cross-section
