摘要：
Evaporation residue production in cold fusion reactions of Pb- and Bi- target nuclei with projectiles of elements between Ti (Z = 22) and Zn (Z = 30) leading to compound nuclei Z(CN) = 104-113 was investigated at SHIP. The result was the first unambiguous identification of isotopes of elements Z = 110, Z = 111 and Z = 112 in bombardments of Pb-208,Bi-209 with Ni-62,Ni-64, Zn-70. We further report on the identification of (256)Db, Lr-252 and on new, improved decay data of Lr-253, (255)Rf, (257)Db, allowing a first deeper insight in the nuclear structure of these isotopes.
