Neutron-deficient uranium isotopes were studied via α spectroscopic methods. A low-lying α-decaying isomeric state was found in ²¹⁸U. The new isomeric state was assigned spin and parity Iπ=8⁺. The isomer decays by α emission with an energy E = 10678(17)keV and with a half-life T1/2 = (0.56⁺⁰·²⁶-₀.₁₄)ms. The known alpha-decay properties of the ground state of ²¹⁸U was measured with improved statistics. The ground-state α-decay has an energy E = 8612(9)keV and a half-life T1/2 =...[Show more]
