Background: The quenching of spin-isospin modes in nuclei is an important field of research in nuclear structure. It has an impact on astrophysical reaction rates and on fundamental processes like neutrinoless double-β decay. Gamow-Teller (GT) and spinflip M1 strengths are quenched. Concerning the latter, the J = 1 resonance in the doubly magic nucleus Ca, dominated by a single transition, serves as a reference case. Purpose: The aim of the present work is a search for weak M1 transitions in Ca with a high-resolution (p, p′) experiment at 295 MeV and forward angles including 0◦ and a comparison to results from a similar study using backward-angle electron scattering at low momentum transfers in order to estimate their contribution to the total B(M1) strength in Ca.
