摘要：

Neutron deficient isotopes of elements Z = 86-92 have been produced by heavy-ion fusion reactions C-12 + Pb-208, Bi-209, Ne-22 + Pb-208; V-51 + Er-170, and Ti-50 + Er-170. The evaporation residues were investigated by means of alpha- and alpha-gamma -spectroscopy after in-flight separation from the projectile beam by the velocity filter SHIP and implantation into a 16-strip position-sensitive Si-detector. New or improved decay data for U-225,U-226, Pa-216,Pa-217m,Pa-218, Th-215,Th-216,Th-217, Ac-214,Ac-215,Ac-216,Ac-216m, Ra-214 and Rn-213 have been obtained.
