摘要：

The B(E2) values of the 136, 367 and 707 keV levels of 57Fe and the 847 keV level of 56Fe are measured. From angular distribution measurements of the decay gamma rays, the E2/M1 mixing ratios are determined. Together with previously determined branching ratios, these data are used to obtain lifetimes of the levels, which are compared with directly measured lifetimes. The Doppler-shift method is used to determine the lifetimes of the 367 and 707 keV levels of 57Fe and the 847 keV level of 56Fe. The magnetic moment of the 136 keV level of 57Fe is determined by an integral-precession measurement in an external field. An attempt is made to observe the magnetic moment of the 367 keV state following implantation in an iron environment. All the properties of the levels in 57Fe are compared with recent theories. © 1969.
