The article reports that photoinduced phase transition in vanadium oxide involves ultrafast loss of coherence. It mentions that the author differentiated the two possibilities of a displacive and of an order-disorder transition by measuring not only the dynamical changes in the Bragg peaks after photoexcitation, but also those x-ray photons scattered in the weak "halo" between peaks.
