Pr2Zr2O7 is a candidate for quantum spin ice behavior, which can be studied in details since large single crystals are now available. Recent neutron data show a broadening of the "pinch points" and a signal dominated by the inelastic contribution. We propose to measure the diffuse scattering maps using polarized neutrons on D7, at 3 temperatures, 15K, 1.7K and 0.1K. With respect to the classical spin ice Ho2Ti2O7,we expect the SF and NSF contributions to be quite similar due to the influence of quantum fluctuations. Simulations of the maps will allow to check the crystal field and energy terms derived from inelastic neutron scattering studies, currently in process.
