## Abstract A variant of the transcorrelated method of Boys and Handy employing finite differences is presented. It is based upon the following two properties of the transcorrelated Hamiltonian operator __C__^โˆ’1^__HC__: (1) __C__^โˆ’1^__HC__ possesses an energy eigenvalue spectrum which is identical
