AB A powerful method of investigating proton-unbound nuclear states by tracking their decay prod-ucts in °ight is discussed in details. To verify the method, four known levels in 15F, 16Ne, and19Na were investigated by measuring the angular correlations between protons and the respectiveheavy-ion fragments stemming from the precursor decays in °ight. The parent nuclei of interest wereproduced in nuclear reactions of one-neutron removal from 17Ne and 20Mg projectiles at energiesof 410{450 A MeV. The trajectories of the respective decay products, 14O+p+p and 18Ne+p+p,were measured by applying a tracking technique with micro-strip detectors. These data were usedto reconstruct the angular correlations of the fragments which provided information on energiesand widths of the parent states. In addition for reproducing properties of known states, evidencefor hitherto unknown excited states in 15F and 16Ne was found. This tracking technique has anadvantage in studies of exotic nuclei beyond the proton drip line measuring the resonance energiesand widths with a high precision although by using low-intensity beams and very thick targets.
