Abstract

The paper presents calculation of the radiative recombination (RR) cross-sections of cold electron with proton and deuteron via the two-step radiative recombination (TSRR) process. TSRR occurs in a virtual excited state which, to conserve momentum, decays to the ground state with the emission of a photon. The RR process due to the dipole interaction leading to the spontaneous photo-recombination (SRR), which is known for a long time, can not fully explain the recent experimental data. The radiative recombination is computed for TSRR channels using field theory and Coulomb gauge. Sum of the recombination rates from SRR and TSRR channels is compared with the experimental results.
