Abstract The elasticα-scattering from40Ca has been studied betweenE α=7.035 MeV and 7.405 MeV. Angular distributions and excitation functions have been measured in 5 keV steps. The data display a resonance atE α=7.26 MeV which by its width and angular correlation is clearly distinguished from strong Ericson fluctuations in this region. From the analysis of the angular distributions and excitation functions a spinJ π=1− is assigned to this resonance. The resonance parameters areΓ α=31 KeV,Γ total=51keV. By its spin and excitation energy this state is interpreted as a member of a quasimolecular band in44Ti the higherl-members of which are known from401Ca(α, α) scattering betweenE α=18 MeV and 50 MeV. The experimental data are compared with recent microscopic calculations within a fully antisymmetrized reaction theory.
