Abstract

The electric quadrupole moments of the 9/2− and 21/2− isomeric states of 173Ta at 165.8 keV and 1713.2 keV, respectively, were measured as Q(9/2−)=2.92(15) b and Q(21/2−)=6.23(18) b for the first time using the TDPAD technique. A 66 MeV pulsed 12C ion beam from the 15UD pelletron accelerator facility of the Nuclear Science Centre at New Delhi was used in the reaction 165Ho(12C, 4nγ)173Ta. The experimental values of equilibrium deformations β2(9/2−)=0.251(7) and β2(21/2−)=0.391(7) were extracted.
