Total and state-selective electron capture cross sections for $\mathbfB^4++\mathrmH$ collisions
Electron capture cross sections for B4++H collisions are calculated using a two-center atomic orbital close coupling expansion method. Total electron capture cross sections are shown to compare well with the recent experimental data of Pieksma et al. [Phys. Rev. A 57, 1892 (1998)] and with the molecular expansion calculation of Shimakura et al. [Phys. Rev. A 47, 3930 (1993)], but not with the molecular calculation of Fraija et al. [Phys. Rev. A 49, 272 (1994)]. Subshell electron capture cross sections are also compared.
