Abstract

The systematics of the πh11/2⊗vh11/2 and πh11/2⊗vs1/2 isomeric configurations were studied for the odd-Z N=77 isotones near the proton dripline. The spin and parity of Iπ = 8+ and 5- were deduced for the isomers in 140Eu and 142Tb. No evidence for the expected 1+ ground-state was found in the 144Ho decay data. The proton emission from 146Tm was restudied and the spin and parity values of Iπ=10+ and 5- were established for 146mTm and 146gsTm, respectively. The interpretation of the observed decay properties and structure of the proton-emitting states was made by accounting for deformation and proton and neutron coupling to the core excitations.
