抄録

We investigated acoustic phonons of PrFeAsO_1-y precisely to select between two different models: the in-plane soft and clipped. These predict different contamination of the longitudinal phonon by transverse one. We could reduce the contamination with improved Q resolution, but the data quality was insufficient.Based on Q dependence slightly better agreement was found with the in-plane soft model.
