If you are on a personal connection, like at home, you can run an anti-virus scan on your device to make sure it is not infected with malware. • The two general kinds of nuclear reactions are nuclear decay reactions and nuclear transmutation reactions.In a nuclear decay reaction, also called radioactive decay, an unstable nucleus emits radiation and is transformed into the nucleus of one or more other elements.The resulting daughter nuclei have a lower mass and are lower in energy (more stable) than the parent nucleus that decayed. 2. Explain why the atomic number is called the, 3. carried out by M.Fleishman and S.Pons in the March of 1989 [1] and revealed for the first time the phenomenon called the cold nuclear fusion (or Low Energy Nuclear Reactions-LENR), i.e. It is also known as nuclear fusion and the formation of new nuclei. 1. Transmutation, conversion of one chemical element into another. It is possible, through nuclear reactions, to transmute long-lived radionuclides into shorter-lived or stable nuclides. When neutrons are required for transmutation reactions, they are usually obtained from radioactive decay reactions or from various nuclear reactions occurring in nuclear reactors. The process of the transmutation of fertile materials to fissile materials is referred to as fuel breeding. This occurs in the main sequence of stars. ), such as neutron capture, or occur spontaneously by radioactive decay, such as alpha decay and beta decay (qq.v. This is known as the origin of light elements. It was created by bombardment of molybdenum by deuterons. 13. 72 8 1NHe OH+⎯⎯→+ In this reaction, a nitrogen nucleus reacted with a high speed helium nucleus to form two new nuclei a 17O and a proton.
