DESCRIPTION:Speakers: Roman Pritula (MEPhI)\nThe method of selection of us
 eful events in the stopped pion absorption reactions has been developed. T
 he method is based on the use the system of monitor semiconductor detector
 s calibrated using registration of pion stops in the “living” target (
 a silicium detector). The monitor system energy threshold values are deter
 mined that allow to reach the maximum efficiency (~ 90%) of the selection 
 of pion stops in the targets.\n\nThe method was tested on the experimental
  data obtained on targets 6\,7Li\, 9Be\, 10\,11B\, 12C\, 28Si\, 40Ca\, 59C
 o\, 93Nb\, 114\,117\,120\,124Sn\, 169Tm\, 181Ta\, 209Bi. It is shown based
  on the analysis of the systematical errors that the absolute normalizatio
 n precision of spectra with the method is 8%. This precision is significan
 tly better than the results obtained with other methods.\n\nhttps://indico
