A simp!e ansat;: for the gound state of atoms and molecules is proposed which is also suitable for large internuclear dis-tanc~ where pertrxbation theory breaks down. In its simplest form, where only doubly+xcited configurations are included, the ansatz leads to 97.3% of the exact correhtion energy
