PHOTODETACHMENT OF THE 2P(2)(P-3(E)) STATE OF H-

Results of semiempirical, adiabatic hyperspherical calculations are pr esented for the photodetachement cross section of the process H- 2p(2) (P-3(e)) + gamma --> H(n = 2) + e(-) at photon energies in the range from threshold to 0.125 a.u. above. We find the detachment cross secti on to have a maximum value of 482 Mb at 25.7 meV above threshold, in g ood agreement with results of close-couplin calculations by Jacobs, Bh atia, and Temkin [Astrophys. J. 242, 1278 (1980)]. In contrast to the close-coupling results, however, we find that the detachment cross sec tion rises by a factor of more than 400 from its threshold value to it s maximum.
