Abstract

In the reaction of complete fusion of 48Ca-ions with a 204Pb target, a new α line, related to the decay of a new, previously unknown isotope (249No), has been detected in an experiment carried out at the SHELS separator. The α decay energy (Eα = 9129 keV) and the half-life (T1/2 = 38.1 ± 2.5 ms) are measured using the GABRIELA detector array. The SF branching ratio was estimated (bSF ≤ 0.2%).

新的 249No 同位素

摘要

48 个Ca 离子与204 Pb 靶标完全融合的反应中,在 SHELS 分离器上进行的一项实验中检测到了一条新的 α 谱线,该谱线与一种新的、以前未知的同位素(249 No)的衰变有关. 的α衰变能量(Ë α = 9129千电子伏)和半衰期(Ť 1/2 = 38.1±2.5毫秒)正在使用的GABRIELA探测器阵列测量的。估算了 SF 支化率 ( b SF ≤ 0.2%)。
