A new version of scattering theory is presented as an example of the 
collision of a non-relativistic spinless particle with a structural 
target. The isometric time-dependent wave transformation operators 
have been introduced and the correct expression for the scattering 
S-matrix have been obtained. In the present version the non-physical 
procedures of 'switching-on' and 'switching-off' an interaction do 
not apply.
