Description
The new neutron-deficient nuclei ²⁴⁰Es and ²³⁶Bk were synthesised at the gas-filled recoil separator RITU. They were identified by their radioactive decay chains starting from ²⁴⁰Es produced in the fusion–evaporation reaction ²⁰⁹Bi(³⁴S,3n) ²⁴⁰Es. Half-lives of 6(2)s and 22ˍ₆⁺¹³s were obtained for ²⁴⁰Es and ²³⁶Bk, respectively. Two groups of α particles with energies Eα=8.19(3)MeV and 8.09(3)MeV were unambiguously assigned to ²⁴⁰Es. Electron-capture delayed fission branches with probabilities of...[Show more]
