Abstract: In the reaction of complete fusion of <superscript>48</superscript>Ca-ions with a <superscript>204</superscript>Pb target, a new α line, related to the decay of a new, previously unknown isotope (<superscript>249</superscript>No), has been detected in an experiment carried out at the SHELS separator. The α decay energy (E<subscript>α</subscript> = 9129 keV) and the half-life (T<subscript>1/2</subscript> = 38.1 ± 2.5 ms) are measured using the GABRIELA detector array. The SF branching ratio was estimated (b<subscript>SF</subscript> ≤ 0.2%). [ABSTRACT FROM AUTHOR]
