Webb3 sep. 2024 · Abstract. In this study, we present a combined small-angle neutron and X-ray scattering (SANS and SAXS) study of the nanoscale structure of cortical bone specimens from three different species. The variation of the scattering cross section of elements across the periodic table is very different for neutrons and X-rays.

WebbThe scattered x-rays are collected on a 2-dimensional area detector azimuthally in 360 degrees at a continuous range of scattering angles which deviate from the direct, transmitted beam. The scattering angle, which we define by convention as 2 θ, defines a “probe length” expressed as D = 2π /q, where q = 4 π sin ( θ )/ λ, in which λ ...
