Abstract
The feasibility of the entire process of γ-ray tracking is demonstrated experimentally for the first time. The accuracy of the results is verified by the capability to carry out a Doppler correction of γ -rays emitted in flight. The resolution of the 846.8 keV transition detected with the MARS detector after Coulomb excitation of a 56Fe beam could be improved from approximately 16 up to 4.6 keV (FWHM). This result corresponds to an obtained position resolution of about 6 mm (FWHM).
