High-resolution, vacuum-ultraviolet absorption spectrum of boron trifluoride
Patrick P. Hughes, Amy Beasten, Jacob C. McComb +6
In the course of investigations of thermal neutron detection based on mixtures of BF with other gases, knowledge was required of the photoabsorption cross sections of $^…
Relativistic calculations of and coefficients for strontium dimers
S. G. Porsev, M. S. Safronova, Charles W. Clark
The electric dipole and quadrupole polarizabilities of the state and the and coefficients for the and dim…
Relativistic all-order calculations of Th, Th and Th atomic properties
M. S. Safronova, U. I. Safronova, Charles W. Clark
Excitation energies, term designations, and -factors of Th, Th and Th are determined using a relativistic hybrid configuration interaction (CI) + all-order approach…
Relativistic many-body calculations of van der Waals coefficients for Yb-Li and Yb-Rb dimers
S. G. Porsev, M. S. Safronova, A. Derevianko +1
We derive the relativistic formulas for the van der Waals coefficients of Yb-alkali dimers that correlate to ground and excited separated-atom limits. We calculate and …
