Determination of the partial electron capture- and spontaneous-fission half-lives of254No

  • Short Note
  • Published:
Zeitschrift für Physik A Atomic Nuclei

Abstract

The isotope254No was produced in the fusion reaction48Ca +208Pb. Using the velocity filter SHIP and radiochemical techniques it was found that the nuclide254No with a half-life of 55 s decays byα, EC, and spontaneous-fission. Deduced partial half-lives are (61±2) s forα-decay, (550 +370−160 ) s for EC and [2.2 +2.0−1.0 ]×104 s for spontaneous fission.
