In this work. Molecular dynamics simulation was performed to study the cascade damage evaluation initial from a 250 eV Primary Knock-on Atoms (PKAs) in gold. For this purpose. the simulations were carried out using the molecular dynamics code GRAPE to study the cooling phase of a cascade from the thermodynamic point view. https://www.roneverhart.com/Tokidoki-X-Hello-Kitty-and-Friends-1-Blind-Box/
