An isobaric analog resonance of $$^{69}$$Zn was studied by the resonance elastic scattering of $$p(^{68}Zn,p)$$ with a 5.5-MeV/nucleon $$^{68}$$Zn beam and a thick polyethylene target. The excitation function of the differential cross section of proton elastic scattering was measured around 0 degrees in the laboratory frame by the thick target inverse kinematics method. The angular momentum, and proton and total widths of the resonance assigned using an $$R$$-matrix calculation are in good agreement with earlier measurements performed using normal kinematics, demonstrating that the thick target inverse kinematics method is a useful tool for studying the single particle structures of neutron-rich nuclei.
