Abstract (english)	We perform a systematic study of the α-particle excitation from its ground state 0+1 to the 0+2 resonance. The so-called monopole transition form factor is investigated via an electron scattering experiment in a broad Q2 range (from 0.5 to 5.0 fm−2). The precision of the new data dramatically supersedes that of older sets of data, each covering only a portion of the Q2 range. The new data allow the determination of two coefficients in a low-momentum expansion, leading to a new puzzle. By confronting experiment to state-of-the-art theoretical calculations, we observe that modern nuclear forces, including those derived within chiral effective field theory that are well tested on a variety of observables, fail to reproduce the excitation of the α particle.
