The fock self-consistent field in the multiconfiguration approximation for the helium atom (samosoglasovannoe pole foka v mnogokonfiguratsionnom priblizhenii diya atoma geliya)( Book )

1 edition published in 1965 in English and held by 1 WorldCat member library worldwide

The solution of the Fock equations are presented in two-configuration approximation for the configurations 2p(2), 2s(2), 3d(2), and 3p(2), regarded as excited configurations with respect to the ground configuration of the helium atom. These solutions are used to evaluate the correction to the energy of the ground configuration for various multiconfiguration approximations. The value of the energy as determined by the Fock self-consistent-field method is presented in the six-configuration approximation 1s(2)-2p(2)-2s(2)-3d(2)-3p(2)-2p3p and compared with the experimental energy value.

Configuration interaction in atomic species of beryillium type( Book )

1 edition published in 1963 in English and held by 1 WorldCat member library worldwide

A calculation was made of the effect of configuration interaction on the energy of the ground configuration of the isoelectronic series Li( - ), Be, B(+), C(2+), N(3+), and O(4+) and the calculated energies were compared experimental data. The stability of negative ions of alkali metals was examined. (Author)
Multiconfiguration approximation for the case of equivalent electrons (mnogokonfiguratsionnoe priblizhenie v sluchae ekvivalentnykh elektronov)( Book )

1 edition published in 1966 in English and held by 1 WorldCat member library worldwide

A new method is proposed for formulating an atomic wave function in the multiconfiguration approximation for equivalent electrons, whereby the individual two-electron component terms are described by a linear combination of two-electron wave functions corresponding to different two-electron configurations. The total energy is expressed through radial integrals for atomic species having the configurations 1s(2)2p(N) (N = 2, 3, 4, 5, and 6), with allowance for the configuration 1s(2)2s(2)2p(N-2). Numerical values of the correction to the energy for the two-configuration approximation and numerical values of the weight factor are given for N = 2, 3, and 4. These were obtained by means of analytic orbitals, whose constants were determined in the single-configuration approximation. (Author)
The multiconfiguration approximation for atomic species of helium type (mnogokonfiguratsionnoe priblizhenie v sluchae atomov tipa geliya)( Book )

1 edition published in 1965 in English and held by 1 WorldCat member library worldwide

The multiconfiguration approximation is applied to the ground configuration of atomic species of helium type from H( - ) to C(4+) by a method in which the results of the self-consistent field are used for the ground configuration, while the corrections to the energy for the multiconfiguration approximation are determined with hydrogen-like analytic wave functions. The resulting values of the total energy are compared with the results of application of the method of partial separation of variables and with the experimental data. (Author)
Multiconfiguration approximation for atomic species of lithium type (mnogokonfiguratsionnoe priblizhenie v sluchae atomov tipa litiia)( Book )

1 edition published in 1965 in English and held by 1 WorldCat member library worldwide

A method is proposed, based on the model of two-electron states, for formulating the atomic wave function in a multiconfiguration approximation in which we forego mandatory equality among the radial orbitals with identical sets of values for the principal and orbital quantum numbers. The three-configuration approximation is applied by this method to the two lowest configurations of four atomic species of lithium type on the basis of analytic hydrogen-like orbitals. Orbitals of the Fock self-consistent field are also used in the case of the lithium atom. (Author)
