Disappearing central peak in paraelectric potassium dihydrogen phosphate (KDP)
Abstract
The quasielastic central peak of paraelectric potassium dihydrogen phosphate is suppressed by annealing. The solf-branch Brillouin spectra are then fitted with a classical coupled-mode expression without any deviation that could suggest additional contributions, and with parameters in good agreement with the available data. © 1978 The American Physical Society.
