The new neutron-deficient isotopes 250102, 242Fm and 254Ku have been synthesized by the reactions 233U(22Ne, 5n), 204Pb(40Ar, 2n) and 206Pb(50Ti, 2n), respectively. It is found that spontaneous fission is the main mode of decay. The spontaneous fissi

The studies of atomic nuclei with Z > 100 are closely related to the synthesis of new chemical elements and to the investigation of stability limits for the heaviest nuclides. From the mid-50s these studies have been carried out using intense heavy-i

At the JINR U-300 heavy-ion cyclotron, a 48Ca ion beam has been first produced. Compared with other ions, these ions have great advantages for the synthesis of transuranic and superheavy elements. The extreme neutron excess of the 48Ca nucleus enable

Experiments on radioactive nuclei proton decay are described. The data on two proton emitters detected from the exposure of Ni to Ne 20 and O 16 beams are given. The first emitter (Ne or Mg light isotopes) has a half life of 85±15 msec and emits pro
