When the x-ray source sent out pulses as short as 80 millions of billionths of a second, the researchers could see the first short period of the crystal melting, which occurred in an unexpected way: The atoms diverged from
their initial energy equilibrium while the average crystalline structure remained — a rarely studied behavior that could not have been seen as clearly with other techniques.

initial and final «
equilibrium» states have EXACTLY the same
energy repartition in the conduction, convection, phase and chemical
energy modes.
