Abstract
Neutron inelastic scattering is a straightforward method for investigating the energy and wavevector exchange between pseudospins and their hosting lattice in the critical region of structural phase transitions. However at the Brillouin zone center, G = 0, the scattering geometry K 0 = K demands a measurement at a very small angle, making the experiment extremely difficult. Instead, it is more practical to perform light-scattering experiments with a right-angle geometry, i.e., K 0 ⊥ K , by using intense coherent light from a laser oscillator.
