“…[17][18][19] In Figs In Ref. 4, the systematic of the excitation energy of the 15/2 − , 19/2 − and 23/2 − levels relative to the 11/2 − state for the N = 79 isotones from Nd to Er has been discussed. For the N = 80 odd-Z nuclei and the N = 79 even-Z nuclei, the 15/2 − and 19/2 − states are interpreted as the fully aligned members of coupling the odd h 11/2 nucleon to the 2 + and 4 + core excitations.…”

“…To comprehensively understand the complex structures and their evolutions with neutron and proton number, the systematic investigations are always helpful. [1][2][3][4] For the N = 80 even-even nuclei, such as 138 Ce, 140 Nd, 142 Sm, 144 Gd and 146 Dy, the 2 + excited states are predominantly formed by two neutron holes (ν −2 j ) in the s 1/2 and d 3/2 shells. 1 The 10 + excited states were systematically observed in these even-even nuclei, 1,2,5,6 which were interpreted by excitations of two h 11/2 neutron holes (νh −2 11/2 ) or two h 11/2 proton particles (πh 2 11/2 ).…”

Combining the new spectroscopy results of 144 Tb and previous spectroscopy studies of neighboring nuclei, a systematic investigation on the low-lying spectra in N = 78 ∼ 80 isotones is performed. Good systematics have been found for the coupling patterns which couple the odd nucleon(s), such as πh 11/2 , νh −1 11/2 , πh 2 11/2 , νh −2 11/2 , πh 11/2 νh −1 11/2 , to the 2 + , 4 + , 6 + and 3 − core excitations. It is found that the relative excitation energies of the states formed by coupling h 11/2 proton(s) to the 2 + , 4 + core excitations are pushed up, in contrast with those formed by coupling h 11/2 neutron hole(s) to the 2 + , 4 + core excitations, which are pulled down. According to the systematics, the interpretation that the 17/2 + states observed in 141 Sm and 143 Gd are the fully aligned member of coupling the odd h 11/2 neutron hole to the octupole 3 − core excitation, is explored to the isotones 145 Dy, 142 Eu, and 144 Tb.
