  • Excited States of Positronic Lithium and Beryllium 
    Bubin, Sergiy; Prezhdo, Oleg V. (2013)
    Using a variational method with an explicitly correlated Gaussian basis, we study the eþ-Li and eþ-Be complexes in the ground and lowest excited states with higher spin multiplicity. Our calculations provide rigorous ...
  • Ground and excited S-1 states of the beryllium atom 
    Hornyak, Istvan; Adamowicz, Ludwik; Bubin, Sergiy (American Physical Society, 2019-09-04)
    Benchmark calculations of the total and transition energies of the four lowest S1 states of the beryllium atom are performed. The computational approach is based on variational calculations with finite mass of the nucleus. ...
