CEPA calculations on open‐shell molecules. IV. Electron correlation effects in B1 Rydberg states of H2O
TL;DR: In this paper, the vertical electronic excitation energies of ten 1b1→a1 excited states of H2O belonging to different Rydberg series were calculated with the FRC, SCF, PNO-CI, and CEPA approximations.

MAGNETIC‐FIELD DIP MEASUREMENTS ON THE He–Cd LASER
A. Dienes,T. P. Sosnowski +1 more
TL;DR: In this article, the authors measured the width of the zero-magnetic field power dip for the 4416-A transition of the He-Cd laser and found that the width is proportional to the decay rate of the electric quadrupole moment, γa(2), of the upper laser level.

Simplified Derivation of a One-range Addition Theorem of the Yukawa Potential
TL;DR: The one-range addition theorem for the Yukawa potential was derived in a very simple manner using weakly convergent expansions as mentioned in this paper, and the relation to Sturmian expansions of Coulomb Green functions is pointed out.

Excited-state photon-echo relaxation in Na vapor
TL;DR: The photon-echo technique, extended to excited-state manifoelds, has been used to study collisionally relaxation in two series of electronic transitions in atomic sodium vapor as mentioned in this paper.
