We report on theoretical total cross sections for electron capture from the ground state of atomic hydrogen by fast multiply-charged nuclei and The prior form of the boundary-corrected continuum intermediate states (BCIS) method is used. For a single fixed initial ground-state comprehensive computations are carried out for a sequence of the transitions to the final state with including all the energy degenerate sub-levels The maximal quantum number is respectively set to 4 for and to 5 for to 6 for as well as to 7 for and The reported nine tables provide these state-selective cross sections () and their state-summed counterparts (). The cross sections for the sum over all the final states are evaluated using the exact results of for and the scaled cross sections for The scaling is based on the Oppenheimer rule. In addition to these tables, at the same impact energies 20–3000 keV/amu, the cross sections from the BCIS method are presented graphically in eight figures for the nuclei and This complements our recently published cross sections for electron capture by protons () and alpha particles () from In the present figures, whenever available, the corresponding experimental data are compared with our results for Also included in these comparisons are the corresponding results for from the continuum distorted wave (CDW) method. The cross sections tabulated here can be used in versatile applications ranging from plasma physics and astrophysics through fusion research to ion therapy.
