We report the results of the experiment on synthesizing 287,288Mc isotopes (Z=115) using the fusionevaporation reaction 243Am(48Ca,4n,3n)287,288Mc at the Spectrometer for Heavy Atoms and Nuclear Structure-... We report the results of the experiment on synthesizing 287,288Mc isotopes (Z=115) using the fusionevaporation reaction 243Am(48Ca,4n,3n)287,288Mc at the Spectrometer for Heavy Atoms and Nuclear Structure-2(SHANS2),a gas-filled recoil separator located at the China Accelerator Facility for Superheavy Elements(CAFE2).In total,20 decay chains are attributed to 288Mc and 1 decay chain is assigned to 287Mc.The measured oa-decay properties of 287,288Mc as well as its descendants are consistent with the known data.No additional decay chains originating from the 2n or 5n reaction channels were detected.The excitation function of the 243Am(48Ca,3n)288Mc reaction was measured at the cross-section level of picobarn,which indicates the promising capability for the study of heavy and superheavy nuclei at the facility. 展开更多

Proton-andα-decay spectroscopy can provide valuable information on the nuclear structure and masses of neutron-de cient isotopes.In 1994,the proton drip line of Ac was reached by the detection of207Ac which was identified via the-decay spectroscopy.Four years later,the neighboring proton-unbound nucleus 206Ac was discov-ered. 展开更多

Experiments with 48Ca and 54Cr induced reactions were performed at the gas-filled recoil separator named Spectrometer for Heavy Atoms and Nuclear Structure-2(SHANS2)of the China Accelerator Facility for superheavy Elements(CAFE2).The isotopic distributions of nuclei produced in the reactions of 48Ca+243Am,54Cr+243Am,and 54Cr+238U were investigated.Bombardments were conducted at energies near the respective Coulomb barriers,with the SHANS2 magnetic rigidities set to collect fusion-evaporation residues.α-decay spectroscopy was employed to identify products,revealing 58 different isotopes in these experiments.The analysis indicates that the distribution of nuclides produced in different reactions exhibits clear systematic trends.Based on their mass distributions,these nuclei were attributed to the products from the quasi-fission(QF)process.Additionally,several short-lived fission events were identified and attributed to the fission isomers near the target. 展开更多
