pCI: a parallel configuration interaction software package for high-precision atomic structure calculations
Charles Cheung, Mikhail G. Kozlov, Sergey G. Porsev +3
We introduce the pCI software package for high-precision atomic structure calculations. The standard method of calculation is based on the configuration interaction (CI) method to…
Electron-loss-to-continuum cusp in collisions of U with N and Xe
P. -M. Hillenbrand, K. N. Lyashchenko, S. Hagmann +24
We study the electron-loss-to-continuum (ELC) cusp experimentally and theoretically by comparing the ionization of U projectiles in collisions with N and Xe targets, at…
Optical clocks based on the Cf and Cf ions
S. G. Porsev, U. I. Safronova, M. S. Safronova +4
Recent experimental progress in cooling, trapping, and quantum logic spectroscopy of highly-charged ions (HCIs) made HCIs accessible for high resolution spectroscopy and precision…
Strong relativistic effect on (quasi)resonance electron-capture processes in non-symmetrical heavy ion-atom collisions
Y. S. Kozhedub, A. I. Bondarev, X. Cai +7
(Quasi)resonance electron-capture processes in non-symmetrical heavy ion-atom collisions are studied employing a semiclassical atomic Dirac-Fock-Stu…
Accurate prediction of clock transitions in a highly charged ion with complex electronic structure
C. Cheung, M. S. Safronova, S. G. Porsev +3
We have developed a broadly-applicable approach that drastically increases the ability to accurately predict properties of complex atoms. We applied it to the case of Ir, w…
Doubly differential cross sections for ionization of lithium atom by protons and O ions
A. I. Bondarev, Y. S. Kozhedub, I. I. Tupitsyn +2
We consider single ionization of lithium atom in collisions with and O projectiles. Doubly differential cross sections for ionization are calculated within a relativisti…
