Abstract

This Brief Report reports on the first observation of the $β^{-}$ -delayed $γ$ decay of $^{215}$ Pb, feeding states in $^{215}$ Bi. The $^{215}$ Pb beam was produced using resonant laser ionization and mass separated at the ISOLDE-CERN on-line mass separator. This ensured clean identification of the $γ$ rays as belonging to the decay of $^{215}$ Pb or its $β$ -decay daughters. A half-life of 147(12) s was measured for the $^{215}$ Pb $β$ decay and a level scheme for the daughter nucleus $^{215}$ Bi is proposed, resulting in an extended systematics of the excited states of the neutron-rich Bi isotopes.
