“…Further details of notation, as well as the parametrized case B recombination coefficient for atomic hydrogen α H , are given by Seager, Sasselov, and Scott (1999 Schleicher et al (2008). For the mutual neutralization rate of H − and H + , we use the more recent result of Stenrup, Larson, and Elander (2009). The evolution of the magnetic energy density E B = B 2 /8π is given as…”

We review current ideas on the origin of galactic and extragalactic magnetic fields. We begin by summarizing observations of magnetic fields at cosmological redshifts and on cosmological scales. These observations translate into constraints on the strength and scale magnetic fields must have during the early stages of galaxy formation in order to seed the galactic dynamo. We examine mechanisms for the generation of magnetic fields that operate prior during inflation and during subsequent phase transitions such as electroweak symmetry breaking and the quark-hadron phase transition. The implications of strong primordial magnetic fields for the reionization epoch as well as the first generation of stars is discussed in detail. The exotic, earlyUniverse mechanisms are contrasted with astrophysical processes that generate fields after recombination. For example, a Biermann-type battery can operate in a proto-

“…H + + H − collisions have been studied extensively, from both the experimental [39][40][41][42][43][44] and theoretical [30,31,[45][46][47][48][49][50][51][52] sides. In this respect, the main challenges of a classical description are to describe a stable two-electron target anion and to correctly represent the mutual neutralization process,…”

We propose a classical trajectory Monte Carlo method to describe two-center collisions with two active electrons. The approach is based on switching between standard four-body and three-body descriptions and it is therefore easy to implement. We demonstrate the reliability of the approach for fundamental H+H and H + +H − collisions that neither four-body nor three-body classical methods describe satisfactorily.

“…Studies of reactions involving collisions of atoms or ions (such as penning ionization, associative ionization and mutual neutralization) require inclusion of angular momentum. A partial wave decomposition is performed and the coupled radial Schrödinger equation will be solved for fixed angular momenta [28]. The total cross section for the reaction is obtained by summarizing contributions from partial waves.…”

Abstract. The resonant states of HeH are computed by combining structure calculations at a full configuration interaction level with electron scattering calculations carried out using the Complex-Kohn variational method. We obtain the potential energy curves, autoionization widths, as well as non-adiabatic couplings among the resonant states. Using the non-adiabatic couplings, the adiabatic to diabatic transformation matrix can be obtained. A strict diabatization of the resonant states will be used to study various scattering processes where the resonant states are involved. These processes involve high energy dissociative recombination (DR) and ion-pair formation (RIP), resonant and direct dissociative excitation (DE), penning ionization (PI) as well as mutual neutralization (MN).
