Background beams from isobaric nuclei have been eliminated by combining the dispersion from the energy loss in a uniform Al foil stack with the momentum resolution of an Enge split-pole magnetic spectrograph. Radioisotope concentrations in the following ranges have been measured: <sup>14</sup>C/<sup>12</sup>C = 10<sup>−12</sup> to 10<sup>−13</sup>, <sup>26</sup>Al/<sup>27</sup>Al = 10<sup>−10</sup> to 10<sup>−12</sup>, <sup>32</sup>Si/Si = 10<sup>−8</sup> to 10<sup>−14</sup>, <sup>36</sup>Cl/Cl = 10<sup>−10</sup> to 10<sup>−11</sup>. Particular emphasis was placed on exploring to what extent the technique of identifying and counting individual ions in an accelerator beam can be conveniently used to determine nuclear quantities of interest when the measurement involves very low radioisotope concentrations. We are able to demonstrate the usefulness of this method by measuring the <sup>26</sup>Mg(p, n)<sup>26</sup> Al(7.2 × 10<sup>5</sup> yr) cross section at proton energies in the astrophysically interesting range just above threshold, and by accurately determining the previously poorly known half-life of <sup>32</sup>Si.</p></div>","PeriodicalId":100971,"journal":{"name":"Nuclear Instruments and Methods","volume":"184 1","pages":"Pages 247-268"},"PeriodicalIF":0.0,"publicationDate":"1981-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0029-554X(81)90876-4","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89232950","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}
