Rope trick is the term given by American nuclear physicist John Malik to the curious lines and spikes which emanate from the fireball of nuclear explosions under certain conditions, just after detonation. [1] [2]
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.
The energy of these rays is sometimes sufficient to start photonuclear reactions resulting in emitted neutrons. One such reaction, 14 7 N (γ,n) 13 7 N, is the only natural process other than those induced by cosmic rays in which 13 7 N is produced on Earth. The unstable isotopes remaining from the reaction may subsequently emit positrons by β ...
On August 6, 1945, the US dropped an atomic bomb on Hiroshima -- and newly revealed photos shed light on the preparations for the attack. On August 6, 1945, the US dropped an atomic bomb on ...
It is these reaction products and not the gamma rays which contain most of the energy of the nuclear reactions in the form of kinetic energy. This kinetic energy of the fission and fusion fragments is converted into internal and then radiation energy by approximately following the process of blackbody radiation emitting in the soft X-ray region ...
This reaction was first described by Stuart Thomas Butler in 1950. [1] [2] A simple one-step stripping reaction can be represented as A+a →B+b A + (b+x) a →(A+x) b +b. where A represents the target core, b represents the projectile core, and x is the transferred mass which may represent any number of particles.
Russia, the United States and China have all built new facilities and dug new tunnels at their nuclear test sites in recent years, satellite images obtained exclusively by CNN show, at a time when ...
Nuclear fusion is what powers our sun and thermonuclear weapons. It occurs when atomic nuclei merge, or fuse, together, producing a great deal of energy. If we could harness fusion power, it would ...
