In nuclear physics and nuclear chemistry, a nuclear reaction is a process in which two nuclei, or a nucleus and an external subatomic particle, collide to produce one or more new nuclides. Thus, a nuclear reaction must cause a transformation of at least one nuclide to another. If a nucleus interacts with another … Meer weergeven In 1919, Ernest Rutherford was able to accomplish transmutation of nitrogen into oxygen at the University of Manchester, using alpha particles directed at nitrogen N + α → O + p. This was the first observation of an … Meer weergeven Nuclear reactions may be shown in a form similar to chemical equations, for which invariant mass must balance for each side of the equation, and in which transformations of particles must follow certain conservation laws, such as conservation … Meer weergeven In writing down the reaction equation, in a way analogous to a chemical equation, one may, in addition, give the reaction energy on the right side: Target nucleus + projectile → Final nucleus + ejectile + Q. For the … Meer weergeven In the initial collision which begins the reaction, the particles must approach closely enough so that the short-range strong force can affect them. As most common … Meer weergeven Kinetic energy may be released during the course of a reaction (exothermic reaction) or kinetic energy may have to be supplied for the reaction to take place (endothermic reaction). This can be calculated by reference to a table of very accurate particle rest … Meer weergeven If the reaction equation is balanced, that does not mean that the reaction really occurs. The rate at which reactions occur depends on the energy and the flux of the incident particles, and the reaction cross section. An example of a large repository of reaction … Meer weergeven While the number of possible nuclear reactions is immense, there are several types that are more common, or otherwise notable. Some examples include: • Fusion reactions — two light nuclei join to form a heavier one, with additional particles … Meer weergeven
