摘要:

The report consists of two parts: First it is shown that the initial momentum anisotropy of a PKA of 3 keV is modulated into near isotropy during the collisional phase of displacement cascades using molecular dynamics simulation. Secondly in the case of a PKA of the order of 100 MeV, in which electron-bursts are produced by energetic recoil-atoms, a possible new mechanism of defect-production caused by such electron-bursts is proposed.
