## Abstract Applying many‐particle methods the lowest excitation energy of the exciton is calculated for an insulator with small energy gap. Screening is taken into account by means of a self‐consistent **__k__**‐dependent screening function. At the finite critical gap __G__~c~ the excitation energ
