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