“…For the N=81 nuclei 133Te, 135Xe, 137Ba, 139Ce, 141Nd and l*3Sm, the energy spectra are calculated for states J~= 1/2 +, 3/2 +, 5/2 +, 7/2 +, 9/2 +, 11/2 + and 7/2-, 9/2-, 11/2-; the latter since negative parities have been tentatively assigned [6,7,9] to a few levels near the energy Ex = 2.5 MeV.…”
