In a proof-of-principle measurement, the Maya active target detector was employed for a12C(p, p) resonant elastic scattering experiment in inverse kinematics. The excitation energy region from0 to 3MeV above the proton breakup threshold in 13N was investigated in a single measurement. Byusing the capability of the detector to localize the reaction vertex and record the tracks of the recoilingprotons, data covering a large solid angle could be utilized, at the same time keeping an energy resolutioncomparable with that of direct-kinematics measurements. The excitation spectrum in 13N was fitted usingthe R-matrix formalism. The level parameters extracted are in good agreement with previous studies. Theactive target proved its potential for the study of resonant elastic scattering in inverse kinematics withradioactive beams, when detection efficiency is of primary importance.
