Neutron scattering length of a proton is largely dependent on proton spin polarization (PH), when neutron is polarized. This effect can be utilized for contrast variation in small angle neutron scattering (SANS). In this article, we will report our recent experiment of spin contrast variation study at BL15 TAIKAN in November 2014. For silica-filled SBR rubber sample, we discussed transmission, coherent and incoherent scattering intensity, as a function of PH.
