The level scheme of Tb-147 has been extended to 116 levels and 198 tra
nsitions in two experiments with the OSIRIS Compton suppressed detecto
r array at the HMI Berlin with the reactions Sn-122(P-31, 6n)Tb147 at
160 MeV and Sn-120(P-31, 4n)Tb147 at 152 MeV. Evidence for a new high
spin isomer at E = 7664.1 keV with a lifetime of the order of 2 ns has
been found.
