Intense peaks, superposed on a structureless spectrum, were observed in 151Yb β-delayed proton decay. It is shown that the peak and statistical protons follow the decay of the s 1 2 groundand h 11 2 isomeric states in 151Yb, respectively. It is concluded that the peaks, also seen in 147Dy and 149Er decays, are due to a low density of 1 2 and 3 2 levels at ≈ 4.5 MeV in the N = 82 daughters.
