Measurements of analyzing power forH2(n→, n)H2scattering at 14.1 MeV and comparisons toH2(p→, p)H2

Data for the analyzing power $A_y\left(\theta \right)$ for the elastic scattering of neutrons from deuterons have been measured at 14.1 MeV for the range from 30° to 153° (c.m.) to accuracies between ±0.003 and ±0.006. The results are compared to previous $n-d$ data at 14 MeV and are in significant disagreement with the most recent measurement. The present data are in excellent agreement with a Faddeev calculation by Doleschall. The data are also very similar to $p-d$ scattering data at 14.1 MeV, although systematic deviations are observed at forward angles and near the maximum of $A_y\left(\theta \right)$ at 130°. Recent calculations indicate that Coulomb effects can explain most of these differences, although some features will require further investigation.
