Research using ultrafast X-ray spectroscopy unveils iron's melting and phase behaviour at Earth core pressures.

The process begins with the absorption of X-ray photons by atoms in the material, leading to the ejection of photoelectrons. By analyzing the energy spectrum of these photoelectrons, information about ...
