(Askeri) ATOM PARÇALANMASI, FİSYON: Nötron bombardımanı ile atom çekirdeklerinin parçalanması. Bu işlem neticesinde, uranyum ve plütonyum gibi ağır metaller parçalanarak büyük miktarda enerji meydana getirir
(Tıp) Ortadan bölünme, ana hücrenin iki yeni hücre meydana getirmek üzere ortadan bölünmesi, bu şekilde kendisini gösteren eşeysiz üreme. (Protozoon'da görüldüğü gibi)
(also Nuclear fission) - A nuclear process in which the nuclei of a heavy atom (e g , uranium is split by a neutron, releasing a large amount of energy and additional neutrons
The splitting of heavier atomic nuclei into lighter ones In the case of heavy atoms (e g , uranium, plutonium), this will release energy Fission is how nuclear power plants produce energy
The splitting of the nucleus into at least two other nuclei and the release of a relatively large amount of energy Two or three neutrons are usually released during this type of transformation Fission reactions occur only with heavy elements such as uranium and plutonium
The process whereby an atomic nucleus of appropriate type, after capturing a NEUTRON, splits into (generally) two nuclei of lighter elements, with the release of substantial amounts of energy and two or more neutrons
The splitting of the nucleus of a heavy atom into two lighter nuclei It is accompanied by the release of neutrons, X-rays, gamma rays, and kinetic energy of the fission products It is usually triggered by collision with a neutron, but in some cases can be induced by protons and other particles or gamma rays
Nuclear reaction in which a larger atomic nucleus splits into two or more smaller nuclei with the release of large amounts of energy Nuclear fission has been used on Earth to produce power for nearly 50 years
The splitting of atoms that results in the release of large amounts of energy Two or three neutrons are usually released during this event Fission occurs either naturally or when an atom's nucleus is bombarded by neutrons
A type of nuclear reaction in which a nucleus with a large atomic number breaks into two or more smaller-atomic-number nuclei with the release of energy; reaction used in the atomic bomb and atomic power plants
The division of an atomic nucleus into parts of comparable mass Generally speaking, fission may occur only in heavier nuclei, such as isotopes of uranium and plutonium Atomic bombs derive energy from the fission of uranium or plutonium
The splitting of a heavy nucleus into two or more radioactive nuclei, accompanied by the emission of gamma rays, neutrons and a significant amount of energy Fission usually is initiated by the heavy nucleus absorbing a neutron, but it can also occur spontaneously
The process where a neutron collides with a heavy element like 235U uranium, causing it to fission into two fission fragments, and release some two to three neutrons and approximately 200 MeV of energy The fission fragments are radioactive, and create the primary concern for waste disposal and accident consequences
a nuclear reaction in which a massive nucleus splits into smaller nuclei with the simultaneous release of energy reproduction of some unicellular organisms by division of the cell into two more or less equal parts
The process whereby an atomic nucleus of suitable material is split into (generally) two nuclei of lighter elements with the release of substantial amounts of energy and two or more neutrons
The splitting of a heavy nucleus into two, accompanied by the release of a relatively large amount of energy and usually one or more neutrons It may be spontaneous but usually is due to a nucleus absorbing a neutron and thus becoming unstable
A method of asexual reproduction among the lowest (unicellular) organisms by means of a process of self-division, consisting of gradual division or cleavage of the into two parts, each of which then becomes a separate and independent organisms; as when a cell in an animal or plant, or its germ, undergoes a spontaneous division, and the parts again subdivide
The splitting of a heavy nucleus into two daughter nuclei (which are nuclei of lighter elements), accompanied by the release of a relatively large amount of energy in the form of kinetic energy of the two parts and in the form of emission of neutrons and gamma rays
a process, which, along with fusion, releases energy stored in separated nuclei During fission, a fissionable nucleus such as plutonium absorbs a neutron, becomes unstable and splits into two nuclei, releasing energy Nuclear power is a controlled, self-sustaining fission process; nuclear explosions are an uncontained chain reaction version of the fission process In the detonation of thermonuclear (fusion or hydrogen) bombs, the fission process is the trigger for the more powerful fusion event Fission products are the artificial radioactive offspring of nuclear industries and accidents; their inventories and pathways in the environment are the subject of this Website (Also see activation products, and naturally occurring radiation)
the process whereby the nucleus of a particular heavy element splits into (generally) two nuclei of lighter elements, with the release of substantial amounts of energy
The splitting of a heavy nucleus into two, accompanied by the release of a relatively large amount of heat and generally one or more neutrons It may be spontaneous but usually is due to a nucleus absorbing a neutron
The splitting of a heavy nucleus into two roughly equal parts (which are nuclei of lower-mass elements), accompanied by the release of a relatively large amount of energy in the form of kinetic energy of the two parts and in the form of emission of neutrons and gamma rays
The spontaneous or induced splitting, by particle collision, of a heavy atomic nucleus into a pair of fragments plus some neutrons Controlled induced fission can be used as a source of nuclear power
