| Summary: | Relativistic corrections to order (υ/
c)
2 are applied to the helium excited states 2
1,3P, 3
1,3D,…, 8
1,3K. Simple correlated open-shell wavefunctions are employed and the Breit operators
H
1 through
H
5 treated as perturbations. Account is also taken of mass polarization and lowest-order one electron Lamb shift. The energies thus calculated agree with experiment to within 2.2 cm
−1 or better. |
