Stability of the heaviest elements: K isomer in ²⁵⁰No

NUCLEAR REACTIONS ²⁰⁴Pb(⁴⁸Ca, 2n)²⁵⁰No, E=218.0 MeV; measured evaporation residues (ER), fission (SF) events, ER-electron-SF correlated events, γ(electron)-coin, half-lives of an isomer and the ground state using RITU separator and GREAT spectrometer at the University of Jyvaskyla accelerator facility. ²⁵⁰No; deduced level, isomer, decay modes of the isomer and the ground state. Systematics of energies of isomers in N=148 isomers ²⁴²Pu, ²⁴⁴Cm, ²⁴⁶Cf, ²⁴⁸Fm, ²⁵⁰No. Relevance to the island of stability of superheavy elements.
