Single-electron capture from helium targets by heavy nuclei of charges 1–7
Single-electron capture by multiply charged nuclei from helium atoms is studied by means of the prior form of the four-body boundary-corrected continuum intermediate state (BCIS-4B) method. Computations concern total cross sections for the state-selective () and state-summed () populations at 20–3000 keV/amu. These refer to the collisions of the type . Here, the projectile covers the ions , , , , , and . The reported findings are tabulated for each value of the quantum numbers . The maximum values of the principal quantum number are 4 (, , ), 5 (), 6 () and 7 (, ). The sum over all the states is truncated by selecting an appropriate cutoff value and by subsequently applying the Oppenheimer scaling rule to approximately include the contributions from . The obtained results for and for some final specific states favorably describe the corresponding experimental data. This qualifies the prior form of the BCIS-4B method for further useful applications in several interdisciplinary fields, including astrophysics, thermonuclear fusion, plasma physics and ion therapy in medicine.
