| Abstract: | The decay of the T 1/2 = 420 ns isomer in 151Er has been reinvestigated. The multipolarities of the decaying transitions have been established by measuring the electron conversion coefficients. An I π = 67/2− assignment is proposed for this isomer with a πh 112/4 d 32/1 d 52/−1]⊗νf 7/2 h 9/2 h 112/−1] configuration. |
