摘要：

The death of massive stars due to supernova explosions is a key ingredient in stellar evolution and stellar population synthesis.Electron capture（EC） plays a vital role in supernova explosions.Using the Shell-Model Monte Carlo method,based on the nuclear random phase approximation and linear response theory model for electrons,we study the strong screening EC rates ofFe in pre-supernovae.The results show that the screening rates can decrease by about 18.66%.Our results may become a good foundation for future investigation of the evolution of late-type stars,supernova explosion mechanisms and numerical simulations.
