A057000100016 the Isotopic Composition of the Natural Bromine - A057000100017 Br-79-69%, A057000100018 Br-81-49.31%. A057000100019 Pellets Thicknesses were Obtained by the Weight andA057000100020 Area Measurement. A057000100021 the Weight of Pressed K-Br Pellets, Diameter 1.5 A057000100022 Cm, Area 1.76 Cm**2, Varied Throughout the Stacked ThinA057000100023 K-Br Discs According to Necessary Energy Loss of A057000100024 Protons in Each Discs. A057000100025 About Twenty K-Br Pellets (0.2-0.6 G/CM**2) Were PlacedA057000100026 in an Aluminum Target Holder.
