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/Traditional-Karate-Do-Okinawa-Goju-Ryu-Book-1-The-Fundamental-Techniques-by-Morio-Higaonna-Preowned/
