9910209Stone This award provides funding for a project to calibrate the production rates of Be-10 and Al-26 in quartz due to cosmic ray muon capture. Accurate knowledge of these production rates is important to researchers in the areas of Quaternary geology, paleoclimatology, and geomorphology who depend on measurements of the concentration of these isotopes to determine the age of exposure to the atmosphere of rock surfaces. Muon capture production rates will be calibrated by analyzing quartz for Be-10 and Al-26 in samples of granite taken from a 6-meter depth profile, which will give a clear separation between spallogenic and muon capture production.***

9910209 Stone该奖项为校准由于宇宙射线μ子捕获而在石英中产生Be-10和Al-26的项目提供资金。这些生产率的准确知识是很重要的研究人员在第四纪地质学，古气候学和地貌学领域的依赖于这些同位素的浓度测量，以确定暴露在大气中的岩石表面的年龄。将通过分析从6米深度剖面上采集的花岗岩样品中的Be-10和Al-26石英来校准μ子捕获生产率，这将明确区分散裂和μ子捕获生产。
