Measurement of the Kr XVIII 3d ${}^2{D}_{5/2}$ lifetime at low energy in a unitary Penning trap

Nicholas D. Guise, Joseph N. Tan, Samuel M. Brewer +2

A different technique is used to study the radiative decay of a metastable state in multiply ionized atoms. With use of a unitary Penning trap to selectively capture Kr${}^{17+}$ ion…
