The favourable ternary fission channel is predicted based on the computation of Q value, driving potential, barrier penetrability and relative yield of all potential ternary fragment configurations. For the parent isotopes 302,306,308,120 with LCP 3H, the maximum relative yield is for the combinations that have one fragment respectively as 131,132I and 139Ba, which are nearly magic. However, in the case of310120 with LCP 3H, the combination 145La+162Sm+3H exhibits the maximum relative yield. For the 4He accompanied fission of 302,306,308,310,120 isotopes, the fragmentation that include 139Cs, 140,144Ba and 131Te isotopes, which is in the vicinity of shell closure possess high relative yield. In the case of8Be accompanied ternary breakup of the parent isotopes 302,306,120, the maximum yield is due to the magic neutron shell and near-magic proton shell of 134Te. Whereas, for parent isotopes 308,310,120, it is due to the presence of respective doubly magic 132Sn and near doubly magic 131Sn as one fragment. Therefore, our findings emphasize the prominent role of both high Q value as well as existence of doubly and near doubly magic nuclei in the ternary fission of super heavy even-even isotopes 302,306–310,120, accompanied by light charge particles 3H, 4He and 8Be.</div>","PeriodicalId":37968,"journal":{"name":"Nuclear and Particle Physics Proceedings","volume":"346 ","pages":"Pages 18-26"},"PeriodicalIF":0.0,"publicationDate":"2024-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141691304","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}
