Precise Variational Calculation For The Doubly Excited State (2p^2)^3P^e of Helium
Full text linkHighly precise variational calculations of non-relativistic energies of the
(2p^2)^3P^e state of Helium atom are presented.We get an upper bound energy
E=-0.71050015565678 a.u.,the lowest yet obtained.Comment: 5 pages, 1 tabl
