Measurement of proton polarization in the 208Pb(d, p)209Pb reaction at an incident energy of 20 MeV Original Research Article

Angular distribution measurements of proton polarization in the 208Pb(d, p)209Pb reaction to the ground g9/2 state were made at an incident deuteron energy of 20 MeV using a high efficiency proton polarimeter. Distorted wave Born approximation analysis and continuum discretized coupled channel analysis were performed on the data and compared with measurements of the angular distribution of the vector analyzing power for the same reaction. The result of the calculations predict that the angular distribution of the vector analyzing power should be similar to that of the polarization. However, the experimental data gives different angular distributions. The measured vector analyzing power is well reproduced by the calculations, while the polarization is not well reproduced.
