Abstract
The metastable Be anion has been experimentally investigated using a c rossed laser-negative-ion-beam apparatus. The Be(2 3P) electron affini ty of 261+/-10 meV has been determined by photodetached-electron spect roscopy. It is also demonstrated that the Be(2 3P) excitation energy o f 2.723+/-0.007 eV can be determined by means of a hybrid technique in volving the use of both autodetached- and photodetached-electron spect roscopies.
