AbstraktAbstract
The first measurement of the hypersatellite-satellite two-photon angular correlation function following the electron capture decay of 55Fe was carried out. In particular, two hybrid active pixel detectors were employed to measure the anisotropy parameter βeff2(exp) = 0.097±0.053, which closely agreed with the theoretical value βeff2(theor) = 0.09735, calculated in the electric-dipole approximation. In addition, we also determined the double K-shell vacancy creation probability in this specific electron capture decay with improved accuracy. We found PKK = (1.388±0.037)×10−4, with a systematic error ΔPKK,syst = 0.042×10−4.
