摘要

Abstract > The helium standard of Japan, referred to as HESJ, is an interlaboratory standard for the 3 He/ 4 He ratio. While the ratio of 3 He and 4 He of the HESJ was previously determined by a relative comparison to atmospheric helium, the absolute value of the 3 He/ 4 He ratio of the HESJ has not been directly determined yet. Therefore, it relies on the early measurements of that of atmospheric helium. The accuracy of the absolute 3 He/ 4 He ratios of the atmosphere and other working standards including HESJ is crucial in some applications of helium isotopes, such as tritium‐ 3 He dating, surface‐exposure age determination based on cosmogenic 3 He, and the accurate measurement of the neutron lifetime. In this work, new control samples of helium gases with 3 He/ 4 He ratios of 14, 28, and 42?ppm were fabricated with accuracy of 0.25–0.38% using a gas‐handling system for a neutron lifetime experiment at Japan Proton Accelerator Research Complex. The relative 3 He/ 4 He ratios of these samples and the HESJ were measured using a magnetic‐sector type, single‐focusing, noble gas mass spectrometer with a double collector system. As a result, the absolute 3 He/ 4 He ratio of the HESJ was determined as 27.36?±?0.11?ppm. The atmospheric 3 He/ 4 He ratio was determined as 1.340?±?0.006?ppm, based on this work. </abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> <div class="translation abstracttxt"> <span class="zhankaihshouqi fivelineshidden" id="abstract"> <span>机译：</span><Abstract Type =“Main”XML：Lang =“en”> <标题类型=“main”>抽象</ title> > 日本的氦标准，称为Hesj，是一个互借标准 3 </ sup> 他/ 4 </ sup> 他的比例。虽然的比例 3 </ sup> 他和 4 </ sup> Hesj的他以前由与大气氦氦气相对比较决定，绝对值 3 </ sup> 他/ 4 </ sup> HESJ的比例尚未直接确定。因此，它依赖于大气氦的早期测量。绝对的准确性 3 </ sup> 他/ 4 </ sup> 他的大气和其他工作标准的比例在氦同位素的一些应用中至关重要，例如氚 - 3 </ sup> 他约会，表面暴露年龄测定基于宇宙原性 3 </ sup> 他，以及中子寿命的准确测量。在这项工作中，新的控制氦气的样品 3 </ sup> 他/ 4 </ sup> 他的比例为14,28和42μm？PPM的精度为0.25-0.38％，用于日本质子加速器研究复合体的中子寿命试验。亲戚 3 </ sup> 他/ 4 </ sup> 使用具有双电集电极系统的磁扇型，单聚焦，贵巴气体质谱仪测量这些样品和HESJ的比率。结果，绝对的 3 </ sup> 他/ 4 </ sup> HESJ的比例确定为27.36？±0.11？PPM。大气 3 </ sup> 他/ 4 </ sup> 他的比率确定为1.340？±0.006？0.006？PPM，基于这项工作。 </ p> </摘要> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> </div> <div class="record"> <h2 class="all_title" id="enpatent33" >著录项</h2> <ul> <li> <span class="lefttit">来源</span> <div style="width: 86%;vertical-align: text-top;display: inline-block;"> <a href='/journal-foreign-23285/'>《Geochemistry, geophysics, geosystems》</a> <b style="margin: 0 2px;">|</b><span>2018年第10期</span><b style="margin: 0 2px;">|</b><span>共11页</span> </div> </li> <li> <div class="author"> <span class="lefttit">作者</span> <p id="fAuthorthree" class="threelineshidden zhankaihshouqi"> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Mishima Kenji&option=202" target="_blank" rel="nofollow">Mishima Kenji;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Sumino Hirochika&option=202" target="_blank" rel="nofollow">Sumino Hirochika;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Yamada Takahito&option=202" target="_blank" rel="nofollow">Yamada Takahito;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Ieki Sei&option=202" target="_blank" rel="nofollow">Ieki Sei;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Nagakura Naoki&option=202" target="_blank" rel="nofollow">Nagakura Naoki;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Otono Hidetoshi&option=202" target="_blank" rel="nofollow">Otono Hidetoshi;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Oide Hideyuki&option=202" target="_blank" rel="nofollow">Oide Hideyuki;</a> </p> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zkzz" style="display: none;">展开▼</span> </div> </li> <li> <div style="display: flex;"> <span class="lefttit">作者单位</span> <div style="position: relative;margin-left: 3px;max-width: 639px;"> <div class="threelineshidden zhankaihshouqi" id="fOrgthree"> <p>High Energy Accelerator Research Organization (KEK)Tokai Japan;</p> <p>Department of Basic ScienceThe University of TokyoTokyo Japan;</p> <p>Graduate School of ScienceThe University of TokyoTokyo Japan;</p> <p>Graduate School of ScienceThe University of TokyoTokyo Japan;</p> <p>Graduate School of ScienceThe University of TokyoTokyo Japan;</p> <p>RCAPPKyushu UniversityFukuoka Japan;</p> <p>Graduate School of ScienceThe University of TokyoTokyo Japan;</p> </div> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zhdw" style="display: none;">展开▼</span> </div> </div> </li> <li > <span class="lefttit">收录信息</span> <span style="width: 86%;vertical-align: text-top;display: inline-block;"></span> </li> <li> <span class="lefttit">原文格式</span> <span>PDF</span> </li> <li> <span class="lefttit">正文语种</span> <span>eng</span> </li> <li> <span class="lefttit">中图分类</span> <span><a href="https://www.zhangqiaokeyan.com/clc/163.html" title="地球物理学">地球物理学;</a></span> </li> <li class="antistop"> <span class="lefttit">关键词</span> <p style="width: 86%;vertical-align: text-top;"> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=helium isotopes&option=203" rel="nofollow">helium isotopes;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=noble gas mass spectrometry&option=203" rel="nofollow">noble gas mass spectrometry;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=helium standard of Japan&option=203" rel="nofollow">helium standard of Japan;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=atmospheric 3He/4He ratio&option=203" rel="nofollow">atmospheric 3He/4He ratio;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=neutron lifetime measurement&option=203" rel="nofollow">neutron lifetime measurement;</a> </p> <div class="translation"> 机译：氦同位素;高贵的气体质谱;日本氦标准;大气3HE / 4HE比率;中子寿命测量;
