Abstract

We have carried out a large R-matrix with pseudostates (RMPS) calculation of the electron-impact excitation of neutral boron. The RMPS method has been employed for the excitation/ionization of many light fusion related species, but primarily for one or two active electrons. The present 640-term close-coupling calculation included three distinct pseudostate expansions. This enabled us to both converge the N-electron structure for three active open-shell electrons and accurately represent the high Rydberg and target continuum states. The derived Maxwell-averaged effective collision strengths will be employed to model the spectral emission from boron, which is of importance to both current (TEXTOR) and future ( ITER) magnetic fusion reactors. The full set of effective collision strengths is available at the Oak Ridge National Laboratory Controlled Fusion Atomic Data Center Web site.
