Four-body Faddeev-Yakubovsky calculation of polarization transfer coefficient ${\mathbf{K}}_y^{y^{\prime }}$ in the ${}^2$H$(\vec{\mathbf{d}},\vec{\mathbf{p}}{)}^3$H reaction at very low energies

Abstract

The polarization transfer coefficient $K_y^{y^{\prime }}$ for the ${}^2$H$(\vec{d},\vec{p}{)}^3$H reaction at energies $E_{lab.}=30$, 50, 70, and 90keV is calculated using the four-body Faddeev-Yakubovsky equation. We employ a separable type of the Paris potential. The experimental data [Phys. Rev. {\bf C64}, 047601 (2001)] agrees with our solution at the scattering angle ${\theta }_{c.m.}=0^{\circ }$, and there is no discrepancy pointed out in that paper. We found that the $K_y^{y^{\prime }}$ is sensitive to the incident deuteron energy at this angle.
