The use of a 7-Be target implanted A025100100017 in copper eliminates the backscattering loss. A025100100018 DETECTOR (SIBAR) A025100100019 METHOD (BCINT,SITA) A025100100020 COMMENT -By Authors: the main feature of the present A025100100021 measurement is the use of a small-size target, A025100100022 implanted into a low-Z material and a uniformly scannedA025100100023 particle beam larger than the target.
