M099700100010 INC-SOURCE (BRST,KINDT) M099700100011 METHOD (COINC) M099700100012 DETECTOR (TRD) The cloud chamber had a diameter 30 cm and depth M099700100013 8 cm. M099700100014 The applied magnetic field had a strength of 5500 M099700100015 gauss the inhomogeneity of the field did not exceed M099700100016 2%. M099700100017 SAMPLE The cloud chamber was filled with helium as a target. M099700100018 ANALYSIS All nuclear reactions due to g-quanta were identified M099700100019 directly by scanning of cloud chamber pictures. M099700100020 ERR-ANALYS (ERR-S) The statistical errors. M099700100021 (ERR-1) Errors in the determination of the magnetic M099700100022 field strength, errors due to the M099700100023 nonuniformity of the magnetic field, to the M099700100024 fluctuations in the magnitizing current, and M099700100025 the errors in the curvature of the emerging M099700100026 particles. M099700100027 (ERR-2,2.5,4.0) The rms error associated with the M099700100028 measurement of curvatures and angles. M099700100029 (ERR-3) The error in absolute value for the intensity M099700100030 of the radiation.
