Description
The excitation of the P11 resonance N(1440) is investigated in inelastic α-scattering on hydrogen using α-particles from Saturne with a beam momentum of 7 GeV/c. In the missing mass spectra of the scattered α-particles two effects are observed, excitation of the projectile, preferentially excited to the Δ resonance, and excitation of the Roper resonance. The large differential cross sections indicate a structure of a compression mode from which the compressibility of the nucleon KN is deduced to be 1.4 ± 0.3 GeV
