## Abstract The ^2^__S__ ground state of lithium iso–electronic sequence is calculated by the use of Hylleraas‐type wave functions. A 92 term one‐spin wave function was used for lithium atom calculations. The energy obtained was −7.478031 a.u. as compared with the previous best value of −7.478025 a

An analysis of the ground state of arsine is performed by using all the line assignments coming from a recent investigation of the vibrational system 2n 2 /n 2 / n 4 /2n 4 /n 1 /n 3 at 1650-2350 cm 01 . A set of 6837 ground state combination differences is used, in combination with all FIR and radio
It is possible to calculate the ground-state wave function and energy of a periodic solid by applying quantum chemical methods. The accuracy achieved is comparable with that for small molecules. The many-body problem of the correlated ground state is expressed in terms of cumulant scattering matrice
