The experiments were carried out with use of the recoil-nucleus kinematic separator Vasilisa. Data were obtained on the characteristics of the radioactive decay of two isotopes: {sup 225}U({ital E}{alpha}=7.87{plus minus}0.02 MeV, {ital T}{sub 1/2}=0.03{sup +0.02}{sub {minus}0.01} sec) and {sup 226}U({ital E}{alpha}=7.57{plus minus}0.02 MeV, {ital T}{sub 1/2}=0.25{sup +0.15}{sub {minus}0.10} sec). The decay characteristics for the previously known nuclides {sup 214} Ac, {sup 223}Th, and {sup 219,220} Ra have been refined. It is shown that in the region of fissile nuclei there is an additional factor which increases the relative yield of ({alpha},{ital xn}) reactions. Attention is called to the possible use of data on ({alpha},{ital xn}) reaction cross sections for investigation of the dependence of the height of the fission barrier on the excitation energy of the nucleus.
