Description

The β-delayed proton decay of 147Er is studied experimentally using the 68Ni+92 Mo reaction at a beam energy of 383 MeV. Based on a He-jet apparatus coupled with a tape transport system, the β-delayed proton radioactivities both from the νs1/2 ground state and the νh11/2 isomer in 147Er are identified by proton-γ coincidence measurements. By analyzing the time distribution of the 4+ → 2+γ transition in the grand-daughter nucleus 146Dy, a half-life of 1.6 ± 0.2 s is determined for the νh11/2 isomer in 147Er. The half-life for the ground state of 147Er is estimated to be 3.2 ± 1.2 s. (nuclear physics)
