This study details the experimental investigation of $^{208}$Pb nuclei excitation through the inelastic scattering of a 155 MeV proton beam. The measurements were carried out at the Cyclotron Centre Bronowice (CCB) IFJ PAN, utilizing a multi-detector setup designed to capture the complex decay patterns of the excited targets.
The experimental configuration comprised the KRATTA triple-telescope array (32 detectors) for the detection and identification of scattered protons, complemented by the PARIS phoswich array and four LaBr$_3$(Ce) scintillators for high-energy gamma-ray spectrometry. The analytical workflow focused on rigorous energy calibration and the synchronization of the timing signals between the different arrays to isolate true coincidence events from the background.
A central part of the analysis was the construction of $E_X-E_\gamma$ coincidence matrices, in which the excitation energy $E_X$, reconstructed from the kinematics of the scattered protons, was correlated with the energy $E_\gamma$ of the coincident gamma rays. Gamma-ray energy spectra were extracted for selected excitation-energy intervals, enabling the investigation of transitions connecting excited states of $^{208}$Pb with its ground state. The developed calibration and coincidence-selection provide a basis for the extraction of the gamma-decay signal associated with the Giant Quadrupole Resonance (GQR) in $^{208}$Pb.
