摘要:

$^{21}$ Mg的β延迟质子发射已在欧洲核子研究中心的ISOLDE进行了测量,其检测装置包括粒子识别能力。$β$延迟质子的质心能量在0.39 $\,$ MeV和7.2 $\,$ MeV之间进行测量,并用于确定$^{21}$ Mg的半衰期为$118.6\pm 0.5\,$ ms。从$βp$分支的线形拟合中,我们提取有关$^{21}$ Na共振的光谱信息。最后,根据反应研究中得到的结果,提出了一种改进的解释的衰变计划。

英文摘要:

Beta-delayed proton emission from $^{21}$Mg has been measured at ISOLDE, CERN, with a detection setup including particle identification capabilities. $β$-delayed protons with center of mass energies between 0.39$\,$MeV and 7.2$\,$MeV were measured and used to determine the half life of $^{21}$Mg as $118.6\pm 0.5\,$ms. From a line shape fit of the $βp$ branches we extract spectroscopic information about the resonances of $^{21}$Na. Finally an improved interpretation of the decay scheme in accordance with the results obtained in reaction studies is presented.
