采用实时数字采集技术高精度测量$^{19}$ Ne Half-life
High Precision Measurement of the $^{19}$Ne Half-life using real-time digital acquisition
摘要：
$^{19}$ Ne的半衰期已经使用实时数字多参数采集系统测量，该系统提供关于每个衰变事件的检测器信号的准确时间戳和相关信息。对数据的详尽离线分析提供了对可能使测量产生偏差的实验效应的独特访问。在建立了影响测量的影响因素，如后脉冲，堆积，增益和基线波动，他们的影响进行了准确的估计和事件的选择优化。得到的半衰期$17.2569\pm0.0019_{(stat)}\pm0.0009_{(syst)}$~s是迄今为止对$^{19}$ Ne最精确的。发现它与最近的两次精确测量一致，但与最近的一次不一致[L.J. Broussard {\it et al.}，物理修订版信函{\bf 112}，212301（2014）]，标准差为3.0。核的半衰期为几秒钟的技术的全部潜力进行了讨论。
英文摘要：
The half-life of $^{19}$Ne has been measured using a real-time digital multiparametric acquisition system providing an accurate time-stamp and relevant information on the detectors signals for each decay event. An exhaustive offline analysis of the data gave unique access to experimental effects potentially biasing the measurement. After establishing the influence factors impacting the measurement such as after-pulses, pile-up, gain and base line fluctuations, their effects were accurately estimated and the event selection optimized. The resulting half-life, $17.2569\pm0.0019_{(stat)}\pm0.0009_{(syst)}$~s, is the most precise up to now for $^{19}$Ne. It is found in agreement with two recent precise measurements and not consistent with the most recent one [L.J. Broussard {\it et al.}, Phys. Rev. Lett. {\bf112}, 212301 (2014)] by 3.0 standard deviations. The full potential of the technique for nuclei with half-lives of a few seconds is discussed.
