 Evidence for a Three-Phonon Giant Resonance State in $^{40}$Ca Nuclei
 INDRA Collaboration(s)
 (2006)
 Inelastic scattering of $^{40}$Ca on $^{40}$Ca at 50 MeV/A has been measured in coincidence with protons at the GANIL facility. The SPEG spectrometer was associated with 240 CsI(Tl) scintillators of the INDRA 4$\pi$ array, allowing for the measurement of complete decay events. The missing energy method was applied to these events. For events with excitation energy between 42 and 55 MeV, a direct decay branch by three protons towards the low energy states of $^{37}$Cl gives the first evidence for a 3-phonon state built with giant resonances.
