Abstract: 
The enhancement of electron-ion radiative-recombination rates at low energies remains an open issue, particularly following the proposal of field-induced recombination (FIR) as a potential mechanism and the corresponding calculations by H & ouml;rndl et al. [ Phys. Rev. A 74, 052712 (2006) ]. We present a refined model for FIR and radiative stabilization, incorporating a two-step cascade process. Our simulations determine the bound-state distribution P(n, l), revealing a turning point at low principal quantum numbers that underscores the limitations of previous extrapolations. Furthermore, we show that in regions with high n and low l, P(n, l) exceeds the statistical approximation, P(n, l) = P(n)2l+1 n2 , due to the influence of a magnetic field. With an expanded sample size of at least 1 x 1011 trajectories, our model accurately estimates recombination rates for bare ions, including He2+, N7+, C6+, Ne10+, Si14+, and Cl17+, achieving excellent agreement with experimental data.
