Abstract:

The multiconfiguration approximation is used to determine the specific effect of mass on the energy of the ground configuration of the helium atom and the positive lithium ion, while the effect is determined in a single-configuration approximation for the configurations lsnpn2,...,6 on the basis of orbitals of the Fock self-consistent field. The energy values of the isotope shift contributed by the mass effect are given for the isotopes of the helium atom of masses 4 and 3 and compare them with experimental data. The shift of a number of spectral lines for the isotopes of the helium atom of masses 4 and 3 and the isotopes of the positive lithium ion of masses 7 and 6 is determined with a rejection of the approximation of the one-electron-state model. The results obtained are compared with the results determined in an approximation of the one-electron-state model based on analytic orbitals, and with experimental data in cases where such data are available.
