A summary is given of the results of experimental determinations of the atomic photo-ionization cross-sections of the alkali metals. Detailed calculations on sodium are described, using Hartree-Fock wave functions, and it is shown that the theory is

The dipole radiation emitted by an atom excited by a unidirectional electron beam has a nonuniform angular distribution which is simply related to the percentage polarization P of the radiation emitted perpendicular to the beam. P was first calculate

Reactance matrices for electron collisions with ions in configurations ls22s22p9(q= 1 to 5), calculated by Saraph, Seaton & Shemming (1969), have been fitted to analytic functions of the energy and extrapolated to energies which give bound states wit

Calculations have been made using the central-field, exchange and exchange-polarization approximations. In agreement with previous work it is found that the wave functions are profoundly modified by inclusion of exchange. The exchange radial equation

Part I is concerned with the general theory of anti-symmetric wave functions for continuous states of atomic systems. For an ( N + 1) -electron system the complete wave function is expressed in terms of an expansion involving products of the N -elect

A formulation is given for electron collisions with ions in configurations 1s$^{2}$2s$^{2}$2p$^{q}$ and 1s$^{2}$2s$^{2}$2p$^{6}$3s$^{2}$3p$^{q}$. The main approximation is neglect of coupling to other configurations. Hartree-Fock functions are used f

The ionization problem is first formulated on the assumption of short-range potentials, particular attention being paid to the treatment of electron exchange. For the case of Coulomb potentials, the asymptotic form of the wave function is obtained fo

Collisional excitation of the ground configuration terms of various ions such as O I, O II, O III, NI, N II and S II is of importance in various cosmic sources. The collision strengths defined as Ω,( n ', n ) = k 2 n w n Q ( n → n ′)/ π , have

A hydrogen atom in the ground state scatters an electron with kinetic energy too small for inelastic collisions to occur. The wave function Ψ(r 1 ; r 2 ) of the system has boundary conditions at infinity which must be chosen to allow correctly for t
