Abstract: Fast anticoincidence scheme with one privileged entrance has been developed, made and adjusted for underestimation of background distribution under full absorption peaks of gamma-ray by transformation one track of multichannel pair gamma-ray spectrometer into anticompton spectrometer. Obtained suppression factor of background is from 1.5 to 4 depending on gamma-ray energy.
