Abstract

Isochronous Mass Spectrometry is a practical approach for studying decays of short-lived isomers. However, solely relying on the time stamps between the isomer and ground state does not provide clear sign of decay. To address this issue, we proposed a method for extracting decay time point by analyzing the residuals of time stamps within a window of (20μs, 180μs) after the start of data acquisition. Decay events out of the window were disregarded due to poor accuracy of revolution time. In this paper, we propose a novel approach based on the discrete Fourier transform technique, which was tested by simulation data. We found that the accuracy of the decay time point can be improved, leading to an expanded window of (15μs, 185μs). Furthermore, as the novel method was applied to experimental data, additional five decay events were identified. The newly determined half-life of 94mRu44+ is consistent with the previous value.

识别环内衰变的新方法及其在 94mRu44+ 半衰期估算中的应用
等时质谱法是研究短寿命异构体衰变的一种实用方法。然而,仅仅依靠异构体与基态之间的时间戳并不能提供明确的衰变迹象。针对这一问题,我们提出了一种提取衰变时间点的方法,即分析数据采集开始后(20μs,180μs)窗口内的时间戳残差。由于旋转时间的准确性较差,窗口外的衰变事件不予考虑。本文提出了一种基于离散傅立叶变换技术的新方法,并通过模拟数据进行了测试。我们发现,衰变时间点的精确度可以得到提高,从而使窗口扩大到(15μs, 185μs)。此外,在将新方法应用于实验数据时,还发现了另外五个衰变事件。新测定的 94mRu44+ 的半衰期与之前的值一致。

期刊介绍: Applied Radiation and Isotopes provides a high quality medium for the publication of substantial, original and scientific and technological papers on the development and peaceful application of nuclear, radiation and radionuclide techniques in chemistry, physics, biochemistry, biology, medicine, security, engineering and in the earth, planetary and environmental sciences, all including dosimetry. Nuclear techniques are defined in the broadest sense and both experimental and theoretical papers are welcome. They include the development and use of α- and β-particles, X-rays and γ-rays, neutrons and other nuclear particles and radiations from all sources, including radionuclides, synchrotron sources, cyclotrons and reactors and from the natural environment. The journal aims to publish papers with significance to an international audience, containing substantial novelty and scientific impact. The Editors reserve the rights to reject, with or without external review, papers that do not meet these criteria. Papers dealing with radiation processing, i.e., where radiation is used to bring about a biological, chemical or physical change in a material, should be directed to our sister journal Radiation Physics and Chemistry.
