Birefringence (rotation of polarization plane and spin dichroism) of deuterons in carbon target

TL;DR

This paper investigates the birefringence effects, including polarization rotation and spin dichroism, of deuterons in a carbon target, emphasizing the dependence on deuteron wave functions at small nucleon distances.

Contribution

It provides the first estimation of spin dichroism and polarization rotation angles for deuterons in carbon, highlighting the role of wave function behavior at short distances.

Findings

Birefringence effects are significant for deuterons up to 20 MeV in carbon.

The magnitude of birefringence strongly depends on deuteron wave functions at small nucleon distances.

Estimated rotation angles and spin dichroism values are presented for experimental consideration.

Abstract

Birefringence phenomenon for deuteron with energy up 20 MeV in carbon target is considered. The estimation for spin dichroism and for angle of rotation of polarization plane of deuterons is presented. It is shown that magnitude of the phenomenon strongly depends on behavior of the deuteron wave functions on small distance between nucleon in deuteron.
