Ionization potential of the helium atom.
The ground-state ionization potential of the He4 atom is found to be 5 945 204 223 (42) MHz. Along with lower-order contributions, this result includes all effects of relative order alpha4, alpha(3)m(e)/m(alpha), and alpha(5)ln(2)alpha. Effective operators derived in dimensionally regularized nonrelativistic quantum electrodynamics are employed. The average values of these operators are evaluat...
متن کاملElectron-impact double ionization of a model helium atom
Singleand double-ionization processes in electron scattering from a model helium atom are calculated by a direct solution of the time-dependent Schrödinger equation on a 3D lattice. The Coulomb interaction between the electrons is described by v(r1 ,r2)51/r. and all angular momenta are set to zero. The initial state is a product of the ground state of the model helium atom on a 2D lattice with ...
متن کاملIonization of a model atom by perturbations of the potential
We study the time evolution of the wave function of a particle bound by an attractive d-function potential when it is subjected to time-dependent variations of the binding strength ~parametric excitation!. The simplicity of this model permits certain nonperturbative calculations to be carried out analytically both in one and three dimensions. Thus the survival probability of bound state uu(t)u,...
متن کاملSelection rules in the few-photon double ionization of the helium atom
We analyse selection rules for the emission of two electrons from the helium atom following the absorption of a few photons in an intense laser field. The rules arise, as generalization of the well-studied one-photon case, due to the symmetries of the accessible final states in the two-electron continuum. We show, in particular, that an increase in the number of absorbed photons leads to altern...
متن کاملEqual energy sharing photo double ionization of the Helium atom at 20 and 40eV above threshold
In this article we present TDCS for equal energy sharing kinematics for double photoionization of the helium atom at 20 and 40eV above threshold in the framework of the hyperspherical partial wave theory. This supplements our earlier work [1] in which we were successful in showing fully, gauge independence of the results in our formalism. Also in this work we treat cases in which the Stokes par...
