Studies of 225,226U \alpha -decay chains produced via heavy ion induced fusion reactions of 22Ne + 208Pb \rightarrow 230U and of 18O + 208Pb \rightarrow 226Th were carried out using the JYFL gas-filled magnetic recoil separator RITU. The data obtained for \alpha -decays of 225,226U, 221,222Th, 218Ra and 213Rn concerning their \alpha -particle energies, half-lives and \alpha -decay fine structures are compared to previous investigations.
