Energetic charged ions are able to induce surface modifications and tracks in materialsin a controlled way,leading to a large number of important applications,s
The energy loss of charged partiles in matter has been studied intensively both theoretically and experimentally[1-3].The energy loss of ion in ionized matter i
The X-ray radiation of comets is caused by solar wind ions.The measurement of such X-rays can predict solar activity and“space weather”,which is of great sign
Nickel is the second most abundant transition element after iron in the sun,so the identifications of its spectral lines and electron transitions are very impor
Two-electron-one-photon(TEOP)transition[1]is an ultrafast transition(~fs)of two correlated electrons.During this transition,coupled electron pair jumps simultan
