The new isotope E248 has been identified among the products of the deuteron bombardment of Cf249. It decays principally by electron capture with a half-life of 25\ifmmode±\else\textpm\fi5 minutes and also by the emission of (6.87\ifmmode±\else\textpm\fi0.02)-Mev alpha particles. A branching ratio (\fracE.C.\ensuremathα) of \ensuremath∼400 was determined from the amount of Cf248 formed by electron-capture decay of the new isotope. Partial excitation functions supporting the assignment to mass number 248 are presented.
