Abstract

The systematics of the πh_11/2⊗vh_11/2 and πh_11/2⊗vs_1/2 isomeric configurations were studied for the odd-Z N=77 isotones near the proton dripline. The spin and parity of I^π = 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 I^π=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.
