In the present study, we present results for the electronic momentum density of polyethylene obtained by Compton scattering of X- and γ-ray radiation. Measurements taken along c-axis, which is the axis of the primary carbon chain of an oriented poly

Compton profiles of polycrystalline lithium were measured at 90 and 300 K, using synchrotron radiation. We detected a slight change with temperature, but its magnitude was found to be much smaller than predicted by recent calculations and its depende

An experimental and theoretical analysis of cobalt disilicide Compton profiles is presented. The measurements along [100], [110] and [111] directions of single crystal CoSi2 are performed with use of synchrotron radiation (59.38 keV). There is a good

We use electron momentum density in ice as a tool to quantify order-disorder transitions by comparing Compton profiles differences of ice VI, VII, VIII and XII with respect to ice Ih. Quantitative agreement is found between theory and experiment for
