Abstract

We have measured the $pd$ elastic scattering with an electron-cooled beam of a proton storage ring and an internal jet target operated with HD gas. The accurately known H/D ratio is used to transfer the precision of existing $pp$ scattering data to the $pd$ cross sections. Measurements were performed for proton energies between 200 and 300 MeV in the angular range $11 ° <~ Θ_{c . m .} <~ 29 ° .$ The results are compared to nonrelativistic Faddeev calculations with different nucleon-nucleon interactions and total angular momenta $j <~ 5$ in the $NN$ subsystem. The impact of a genuine $3 N$ force is investigated. The discrepancies between data and calculations increase with projectile energy.
