Abstract

The temperature dependence of the anisotropy of γ-rays from the decay of oriented183,184Re nuclei situated in an iron matrix was measured between 14 and 33 mK. Magnetic hyperfine splitting constants ofgH HF=5.04(9) × 10−18 erg andgH HF=3.21 (13) × 10−18 erg were determined for the groundstates of183Re and184Re, respectively. With the previously known hyperfinefield of −760(15) kG for Re in iron the followingg-factors were deduced:183Reg=1.32 (5) and184Reg=0.84 (5). The E2/M1 mixing ratio of the 793 keV 2+ −2+ transition in184W was accurately determined to δ (793 keV)=+16.65 (85).
