Use of the channeling technique to locate interstitial impurities

Abstract
The channeling technique has been used to locate B11 implanted into various crystals. In some cases, notably in tungsten and iron, a well defined interstitial position is indicated. The main object has been to learn how to extract information about the location of an interstitial impurity from channeling measurements. It appears that sufficient evidence may be obtained only from full angular scans through different axial and planar channelings dips (or peaks).
