The New 249No Isotope
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%).
