Abstract (EN): Conversion electron-gamma PAC measurements of the 49-37 keV cascade in Br-80 through the intermediate 2(-) state with T-1/2 = 7.4 ns were performed with a system of two magnetic lens spectrometers and two BaF2 scintillation detectors. The parent Br-80m activity with a halflife of 4.4 hrs was implanted into Ni, Zn and graphite at the ISOLDE separator at CERN. The observed interaction frequency in the nickel matrix is in good agreement with the known value of the hyperfine field for Br in Ni and the magnetic moment of the 2(-) state. From the measured quadrupole interaction in Zn and graphite the electric field gradients at Br were obtained.
