Instead, the majority of evaluated distributions are based on analytic expressions of the Zp-model for relevant cumulative yields. Here we report independent elemental fission product yield distributions of a 235U target for incident neutron energies ranging from 0.11 MeV through 92.4 MeV. Atomic numbers are calculated by an approach that combines a 2E analysis with a stopping force analysis method, developed within this paper. These analyses are applied to more than 6.1 × 106 fission fragment ionization tracks captured within the NIFFTE (Neutron Induced Fission Fragment Tracking Experiment) collaboration fission time projection chamber (fissionTPC). A 3-Z resolution was obtained with the fissionTPC spatial and energy resolutions. Tabulated results are presented for the atomic yield and experimentally derived Zp values as a function of pre-neutron-emission fragment masses for the complete range of incident neutron energies. The stopping-force-derived Zp values tend to support the unchanged charge distribution theory within uncertainty.</div>","PeriodicalId":49735,"journal":{"name":"Nuclear Data Sheets","volume":"184 ","pages":"Pages 1-28"},"PeriodicalIF":3.7,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46652549","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This evaluation for A=186 supersedes the earlier evaluation 2003Ba44 by C. M. Baglin. Highlights of this evaluation are the following: 186Re: Revised %ε and %β− branches. New values are almost same as of the earlier ones. Adopted improved level energy for the long-lived (8+) isomer at 148.2 keV 5 based on the study reported in 2015Ma60 (187Re(n, 2nγ)) compared to 149 keV 7 in previous evaluation (2003Ba44). 186Hg: Discrepancies in the level schemes between 1992Po01 and 1993Ma02 remain to resolve experimentally, arise primarily due to the assigned multipolarity of the ≈607 keV γ transition between the 1228 keV bandhead and the 2+ 621 keV level. See general comments in Adopted Levels, Gammas dataset. 186Tl: From α decay studies, 2020St11 propose spin-parity (2−) for the g.s. and (7+) for the excited level at 0.0+x of level energy of 77 keV 56.
