Mass Number The sum of the number of protons and neutrons of an atomic nucleus. In other words, it's the sum of the number of nucleons in an atom. Relative Atomic Mass The ratio of the average mass per atom of an isotope to 1/12 the mass of a carbon-12 atom. Relative atomic mas...

THE OBJECT OF THE INVENTION IS A TARGET FOR PRODUCING RAPID NEUTRONS BY REACTION 73 LI (P, N) 74 BE. IT INCLUDES A THIN CLINQUANT OF ALUMINUM 30 SUPPORTED IN A TUBE 10 WITH DIRECTED BEAMS AND IN WHICH A VACUUM HAS BEEN ESTABLISHED BY A WATER-COOLED SUPPORT STRUCTURE 12; THE BREACHS ...
Additionally, to produce the required neutron dose at the object position, both the number of driver protons and their energy need to be greatly increased. As a result, a high dose of γ-rays and neutrons will be distributed at large angles and spoil the advantages of the endothermic ...
The following occurs: lithium nuclei (3 protons + 4 neutrons) are targeted by high-speed protons(hydrogen nuclei), resulting in lithium absorbing a proton to form 4 protons + 4 neutrons,which become two alpha particles (helium nuclei). For example, see the following equation:1H + 3Li = 2...
