摘要: The channeling of the recoiling nucleus in crystalline detectors after a WIMP collision would produce larger scintillation or ionization signal direct detection experiments than otherwise expected. I present estimates fractions obtained using analytic models developed from 1960's onwards to describe and blocking effects. We find be too small affect fits potential candidates. also examine possibility detecting daily modulation dark matter due channeling.
