Spontaneous fission instability of the neutron-deficient No and Rf isotopes: The new isotope ²⁴⁹No

RADIOACTIVITY ^253,253mRf(SF); ²⁵³Rf, ²⁴⁹No(α)[²⁵³Rf from ²⁰⁴Pb(⁵⁰Ti, n), E=234.3 MeV]; measured evaporation residues (ERs), (ER)(fission)- and (ER)α-correlated events, Eα, Iα, partial half-lives of two fission activities of ²⁵³Rf, α-decay half-life of newly discovered ²⁴⁹No isotope from the α decay mode of ²⁵³Rf in (ER)-α-α-α correlated events using gas-filled TransActinide Separator and Chemistry Apparatus (TASCA) at UNILAC, GSI. ²⁵³Rf; deduced another high-lying ≈0.6-μs isomer. ^251mNo; discussed in Supplemental Material of the paper a possible identification method for direct fission from an isomeric state in ²⁵¹No. Presence of two fission activities in ²⁵³Rf proposed as benchmark cases for the theoretical description of the influence of single-particle orbitals on the fission process.
