| Abstract: | Long lens electron spectrometers were used to make electron-gamma and electron-electron PAC measurements for the 5/2+ 13.3 keV state of73Ge. Sources of73As were produced in the decay of73Se implanted at the CERN/ISOLDE facility. The magnetic interaction in nickel was determined as  L=74.2(7) Mrad s–1 and the quadrupolar frequency in antimony asvQ=19.7(2) MHz. The nuclear moments derived are  =–1.08(3) N and |Q|=0.70(8) b. |
