摘要: Abstract It is shown that weakly interacting massive particles (WIMPs), which are possible cold dark matter candidates, can be studied by exclusive measurements of X-rays following WIMPs nuclear interactions. Inner-shell atomic electrons ionized through WIMP-nuclear interaction, and then mono-energetic emitted when they filled outer-shell electrons. The number inner-shell holes amounts to as large one per five recoils for K-shell several recoil L-shell in the case medium heavy target nuclei with 100–300 GeV WIMPs. Then K L X-ray peaks show up 5–50 keV region. Consequently studies coincidence ionization found provide excellent opportunities detect such lightest super-symmetric (LSP).
