The higher energy region of gamma-rays (from 480 to 810 keV) and conversion electrons (from 570 to 760 keV) was studied with a 20 cm3 Ge(Li) and a 3 mm deep Si(Li) semiconductor spectrometer, respectively. For the conversion coefficients and for their ratio, αK = (3,6 ± 0.5) · 10-3 and K/L=5.3±1.6 were obtained at the 636.3 keV transition as well as αK = (3.9 ± 0.6) · 10-3 and K/L=4.7±1,4 at the 722.9 keV transition. On the basis of these and some other published data, the 5/2+ assignment for the 722.9 keV level and the 7/2+ one for the 636.3 keV level seem to be the most probable.
