DESCRIPTION:Generation and detection of spin-orbit coupled neutron beams \n\nStructured waves and spin-orbit coupled beams have become an indispensable probe in both light and matter-wave optics [1-2]\, for neutron specifically\, showing distinct scattering dynamics for some samples [3-4]. We present a method of generating neutron orbital angular momentum (OAM) states utilizing 3He neutron spin filters along with four specifically oriented triangular coils and magnetic field shielding. These states are verified via their spin-dependent intensity profiles [5]. The period and OAM number of these spin-orbit states can be altered dynamically via the magnetic field strength within the coils and the total number of coils to tailor the neutron beam towards a particular application or specific material [6].  \n\n[1] H.
