The specific character of arising of anomalous amplitudes at the detection of rare spontaneous fission events of nuclei implanted into silicon radiation detector has been considered. The analysis was performed within the frameworks of two approaches: dynamic focussing of the electric field by the track of ionizing particle and the model of charge accumulation in the vicinity of the top electrode[1,2]. These conditions were compared with the ones for an external calibration source.
