The new isotope219U

In continuation of our experimental program on investigation of evaporation residues (ER's) in the region close to N=126 [1, 2], the new neutron-deficient isotope²¹⁹U has been produced in the irradiations of an¹⁹⁷Au target with a beam of²⁷A1 ions. The identification of²¹⁹U was made establishing genetic position and time correlations between the implanted ER's with their subsequentα-decays. Theα-decay energy and half-life were measured to be (9680±40) keV and (42 _?13 ⁺³⁴ )μs, respectively. To separate the evaporation residues in-flight the kinematic separator VASSILISSA [3] was used.
