DOI: 10.1134/s1547477118030032
Abstract: Non-relativistic ionization energies 3He2+μ−e− and 4He2+μ−e− of helium-muonic atoms are calculated for ground states. The calculations are based on the variational method of the exponential expansion. Convergence of the variational energies is studied by an… read more here.
