Precise Variational Calculation For The Doubly Excited State (2p^2)^3P^e of Helium

Tapan K. Mukherjee, Prasanta K. Mukherjee

Highly 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…
