High-spin states in the nucleus Te-121 have been populated by the Pd-1
10(O-18,alpha 3n) reaction. gamma-ray energies, intensities, gamma-gam
ma coincidences and DCO ratios have been measured. The level sequence
build on the h(11/2) isomeric state has been extended to spin I greate
r than or equal to 51/2 and to an excitation energy of about 8.5 MeV.
