It has energy dependence close to the CB beam spectrum and depends on the CB peak energy. Thus, in the course of the cross section measurements, the systematic, measurements of the tagging efficiency should be usually produced. The paper shows that tagging efficiency can be estimated computationally by taking into account the background contribution to the detectors of the tagging system. This allows one to get cross sections simultaneously with the cross section asymmetry measurements in the case when the systematic tagging efficiency measurements were not performed.","PeriodicalId":54580,"journal":{"name":"Problems of Atomic Science and Technology","volume":"47 9","pages":""},"PeriodicalIF":0.2,"publicationDate":"2023-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139006934","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
