RUI: Study of 14N and 25Mg Proton Capture Reactions

该提案支持PI和本科生参与低能核加速器实验室（LENA）进行的研究。这些测量的主要重点将是天体物理学感兴趣的低能p-伽马反应。由于许多天体物理测量的兴趣涉及非常低的计数率和大的背景，计算例程将被用来帮助LENA的探测器的设计，最大限度地提高效率和最小化的背景。该提案还将支持PI和本科生参与LENA实验的数据收集和分析。实验室建成后，首先提出的实验是，14-氮（p-γ）15-氧，其结果有望降低S（0）的不确定性，以及25-镁（p-γ）26-铝，其反应速率对应于较低的恒星温度。

This proposal supports participation of the PI and undergraduatestudents in research conducted at the Low Energy Nuclear Acceleratorlaboratory (LENA). The main focus of these measurements will be lowenergy p-gamma reactions of astrophysical interest. Since manymeasurements of astrophysical interest involve very low counting ratesand large backgrounds, computational routines will be used to aid in thedesign of a detector for LENA which maximizes efficiency and minimizesbackground. The proposal will also support participation of the PI andundergraduate students in data collection and analysis for experimentsdone at LENA. The first proposed experiments after completion of thelaboratory are, 14-Nitrogen (p-gamma) 15-Oxygen with results expected toreduce the uncertainty in S(0), and 25-Magnesim (p-gamma) 26-Aluminumaddressing reaction rates for low-lying resonances corresponding tolower stellar temperatures.
