The fock selfconsistent 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 twoconfiguration 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 selfconsistentfield method is presented in the sixconfiguration approximation 1s(2)2p(2)2s(2)3d(2)3p(2)2p3p and compared with the experimental energy value.

)
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 twoelectron component terms are described by a linear combination of twoelectron wave functions corresponding to different twoelectron 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(N2). Numerical values of the correction to the energy for the twoconfiguration 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 singleconfiguration approximation. (Author)

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 selfconsistent field are used for the ground configuration, while the corrections to the energy for the multiconfiguration approximation are determined with hydrogenlike 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 twoelectron 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 threeconfiguration approximation is applied by this method to the two lowest configurations of four atomic species of lithium type on the basis of analytic hydrogenlike orbitals. Orbitals of the Fock selfconsistent field are also used in the case of the lithium atom. (Author)
