英文摘要Molecular dynamics simulations are performed to investigate the behavior of helium atoms generated from tritium decay in copper crystals at 300 K. At the early stage just after a He atom generation, the lattice structure is badly deformed and the local temperature rises considerably above 300 K. In perfect crystals, single He atom diffuses by interstitial paths whereas two He atoms attract each other and can form a stable dimmer, which pushes a Cu atom off its original lattice site and occupies the vacancy. This dimmer can catch another He atom to form a trimmer. In a Cu crystal with a prepared vacancy, single He atom rapidly occupies the vacancy with little lattice deformation.
