| Abstract: | The perturbation of the 197 keV transition angular distribution in F19 was investigated by time-dependent spin rotation measurements following excitation with a pulsed beam. The recoil implantation technique was used to determine the internal magnetic fields for F19 in Fe, Co and Ni lattices. The results are:H HF(F19 in Fe)=+(95700±500) Oe,H HF(F19 in Co)=+(59500±1500) Oe,H HF(F19 in Ni)=?(21830±350)Oe. The temperature and field dependence of the effective fields was studied. Strong satellite fields due to lattice perturbations were detected. The half life and the gyromagnetic ratio of the 197 keV 5/2+ state in F19 were redetermined asT 1/2=(80.2±0.5) nsec andg=+1.436±0.007. |
