“…The directional correlations were measured with the multichannel goniometer MCG developed at this laboratory [7,8]. A version of the apparatus was used in which two of the eight detectors are high resolution Ge(Li) detectors (ORTEC VIP-10) and the remaining six are 3.8 x 5.1 cm NaI(T1) detectors.…”

“…The number of coincidences in the coincident peaks were determined by fitting Gaussian curves on linear backgrounds to narrow regions of the spectra around the respective peaks. The resulting coincidence rates (Cu) were then fitted to the expression [7].…”

Gamma-gamma directional correlations in the decay of206Po

et al. 1981

Directional correlations of gamma-gamma cascades in the decay of 2~ have been measured for the first time. Using a multichannel goniometer with 2Ge(Li) and 6 NaI(Ti) detectors the A 2 and A 4 coefficients have been measured for five cascades in 2~From the results, E2/M1 mixing ratios of nine transitions are determined. Upper limits of the transition strengths are presented. Three of the measured mixing ratios are compared with theoretical estimates based on magnetic dipole and electric quadrupole moments of neighbouring nuclei.

“…(1) One of these was a multichannel goniometer (MCG) with eight NaI(T1) detectors. The MCG and the method of data analysis have been described previously [18]. (2)Further, a two-detector setup with one Ge(Li) detector (36 cm 3) and one NaI(T1) detector was used.…”
