Levels: Data for levels above the 11/2- isomer are from are from ¹⁰²Pd(⁵⁸Ni,3pγ) and those for the ground state and 11/2- isomer are from ¹⁵⁷Lu α decays to ¹⁵³Tm. The ¹⁵⁷Lu ground state decays (1991Le15,1991To09) to the s_1/2 excited level in ¹⁵³Tm and the ¹⁵⁷Lu excited level decays to the h_11/2 ground state of ¹⁵³Tm.
