摘要：

The metastable Be anion has been experimentally investigated using a crossed laser-negative-ion-beam apparatus. The Be(2 3P) electron affinity of 261+/-10 meV has been determined by photodetached-electron spectroscopy. It is also demonstrated that the Be(2 3P) excitation energy of 2.723+/-0.007 eV can be determined by means of a hybrid technique involving the use of both autodetached- and photodetached-electron spectroscopies.
