摘要：

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 isotope 219U has been produced in the irradiations of an Au-197 target with a beam of Al-27 ions. The identification of 219U was made establishing genetic position and time correlations between the implanted ER's with their subsequent alpha-decays. The alpha-decay energy and half-life were measured to be (9680 +/- 40) keV and (42(-13)+34)mus, respectively. To separate the evaporation residues in-flight the kinematic separator VASSILISSA [3] was used.
