Identification of the New Isotope 244Md
(2020) In Physical Review Letters 124(25).- Abstract
- In an experiment performed at Lawrence Berkeley National Laboratory’s 88-inch cyclotron, the isotope 244Md was produced in the 209Bi(40Ar,5n) reaction. Decay properties of 244Md were measured at the focal plane of the Berkeley Gas-filled Separator, and the mass number assignment of A = 244 was confirmed with the apparatus for the identification of nuclide A. The isotope 244Md is reported to have one, possibly two, α-decaying states with α energies of 8.66(2) and 8.31(2) MeV and half-lives of 0.4+0.4-0.1 and ∼6 s, respectively. Additionally, first evidence of the α decay of 236Bk was observed and is reported.
