Abstract : The internal conversion coefficients of the 0.164, 0.272 and 0.484 MeV gamma rays of Ni56 have been determined utilizing a scintillation gamma ray spectrometer and a Siegbahn-Satis intermediate-image beta-ray spectrometer. Respective conversion coefficients of 0.12 = 0.001, 0.0034 = 0.0002 and 0.0015 = 0.00015 were found. Comparison with theoretical conversion coefficients expected for pure multipole transitions and use of the Weisskopf single-particle estimates for the gammaray transition probabilities lend considerable support to an analysis of the low-excited states of Co56 in terms of a simple shell model for an odd nucleus.
