摘要：

The cross section for photodetachment of the P-3 bound state of the negative ion of neutral boron is calculated from threshold to a photon energy of 0.6 Ryd. The calculation employs a multichannel theory based upon the R-matrix method for electron-atom collisions. The cross section shows a targe dip prior to the 2s2p(2) P-4 threshold followed thereafter by a sharp rise. The sharp rise and following maximum are due to quasibound states in the P-3 degrees and D-3 degrees final symmetries.
