Abstract
The energy region from the π threshold up to the Roper resonance N(1440) has been investigated in inelastic α scattering on hydrogen using α particles from SATURNE with a beam momentum of 7 GeV/c. In addition to projectile excitation, excitation of the (1440 MeV) resonance has been observed for the proton, indicating a strong monopole excitation. From this a value of the nucleon compressibility of 1.4±0.3 GeV is extracted.
