Lithium and beryllium

WebBeryllium (Be) has been thought of as an alternative target because of its good thermal and chemical properties and reasonable neutron yield. However, in order to have a neutron yield comparable to that of a thick Li target bombarded with 2.5 MeV protons, the proton energy required for a thick Be target must be approaching 4 MeV. WebBeryllium is the least reactive alkaline earth metal; it has the smallest atomic radius and highest ionization energy of all the Group 2 elements. The surface of beryllium metal forms an oxide passivation layer that protects it from further oxidation or …
