Measurement of the Cross Section and Analyzing Powers for $\vec{\rm d}$+p Elastic Scattering at 180 MeV

We have measured cross sections and analyzing powers for various $\vec{\rm d}$+d reaction channels, including $\vec{\rm d}$+d elastic and $\vec{\rm d}$+d$\to$p+t at 130 MeV and 180~MeV, with the hope of providing a testing ground for new 4-body theoretical predictions. These data were collected at the KVI cyclotron (Groningen) using the Big Bite spectrometer and a polarized deuteron beam. In addition to the $\vec{\rm d}$+d channels, we also measured the cross section and analyzing powers ($A_y$ and $A_{yy}$) for $\vec{\rm d}$+p elastic scattering at the same energies for comparison with existing data and with 3-body calculations (with and without three nucleon forces). We report here our results for the $\vec{\rm d}$+p elastic data at 180 MeV. The analysis procedure will be reviewed and several preliminary results will be shown.
