Figure 1

The longitudinal spin polarization of transmitted electrons, Eq. (26), as function of numbers of base pairs in dsDNA, $N$, for transverse spin polarized, $\delta =\pi /2$ (central solid line) and with small longitudinal component of spin polarization vector, $\delta =\pi /2\mp 0.2$ (parallel and antiparallel to the direction of propagation), incident electrons. Filled circles indicate experimental points for photoelectrons with linearly polarized (central points) and circularly (clockwise and counterclockwise) polarized light at $N=50$ and $N=78$ given in Ref. 4. The effective SO coupling is taken to be ${\alpha }_{\mathrm{SO}}=1.33$ meV nm which corresponds to $q_{\mathrm{SO}}\Delta z=6\times {10}^{-3}$. Other parameters used are $b=34$ Å, $\Delta z=3.4$ Å, $R_0=5$ Å and also correspond to DNA molecule.Reuse & Permissions
