摘要

虽然\(^{14}\) N(p, \(\gamma \)) \(^{15}\) O反应在各种恒星条件下的氢燃烧过程中起着关键作用，但其反应速率尚不清楚。因此，在格兰萨索国家实验室最近启动的贝洛蒂离子束设备上的第一个科学项目是测量质子能量范围在250到1500 keV之间的\(^{14}\) N(p, \(\gamma \)) \(^{15}\) O反应截面。本文综述了固体氮靶的实验技术，重点介绍了固体氮靶的制备和表征。给出了在55 \(^\circ \)检测角下测定反应产率的初步结果。

Towards a comprehensive study of the \(^{14}\)N(p,\(\gamma \))\(^{15}\)O astrophysical key reaction: Description of the experimental technique including novel target preparation

While the \(^{14}\)N(p,\(\gamma \))\(^{15}\)O reaction plays a key role in the hydrogen-burning processes in various stellar conditions, its reaction rate is not known with sufficient precision. Therefore, the first scientific project at the recently launched Bellotti Ion Beam Facility of the Laboratori Nazionali del Gran Sasso was the measurement of the \(^{14}\)N(p,\(\gamma \))\(^{15}\)O reaction cross section in the proton energy range between 250 and 1500 keV. In this paper, the experimental techniques are summarized with special emphasis on the description of solid state nitrogen target production and characterization. The first results of the reaction yield measured at 55\(^\circ \) detection angle are also presented.
