The reaction \(p + d \rightarrow p + d + X\) was studied at 0.8-2.0 GeV proton beam energies with the ANKE magnetic spectrometer at the COSY synchrotron storage ring. The proton-deuteron pairs emerging with high momenta, 0.6-1.8 GeV/\(c\), were detected at small angles with respect to the proton bea...
