Abstract: | Accurate lower and upper bounds for the nonrelativistic lowest energies1 E 0 and3 E 0 of the singlet and triplet-system of the4He-Isotop are calculated with the linearized method of variance minimization. The same was done for1 E 1 the energy of the first excitedS-state 21 S. The results especially for1 E 0 and3 E 0 in a.u. are −2.90330769975 ≤1 E 0 ≤ −2.90330769218 −2.17493242637 ≤3 E 0 ≤ −2.17493242459 i.e. the values are determined with an absolute error smaller than 0.00167 cm−1 for1 E 0 and 0.00039 cm−1 for3 E 0. |
