Term Values in Carbon

Abstract

The energies of the terms of the normal state of C I, $1s^{2}2s^{2}2p^2$, and of the excited state, $1s^{2}2s2p^3$, are calculated with one-electron functions for a self-consistent field. The effect of the interaction of $1s^{2}2s^{2}2p^2$ and $1s^{2}2p^4$ is also included. Tables are given of the radial integrals, of the absolute energies of the terms, and of the separations of the terms. $1s^{2}2s2p^3{}_{}{}^5{}_{}{}^{}S$ is found 3.16 volts above the ground state $2p^2{}_{}{}^3{}_{}{}^{}P$.
