Chain reactions

yet to find an argument that has convinced the public that GM is a green revolution we can ill afford to miss out on. Until ministers do so, GM crops will remain a much talked about idea, but never an eaten foodstuff.” “Proven: environmental dangers that may halt GM revolution” headed The Independent’s coverage. “British scientists delivered a massive blow to the case for genetically modified c...

Nuclear reactions and nuclear ̄ssion

1 Cross sections and reaction rates 2 Consider a thin target of thickness dx and number density of targets nt being bombarded by a beam of number density Nb moving at velocity v. Each target nucleus presents a target area 3⁄4 { if one of the bombarding particles passes within the area 3⁄4, interaction (scattering, for example) occurs, otherwise not. Now if the beam covers an area A, the fractio...

Nuclear Structure and Nuclear Reactions

Atomic nuclei are the essence of the visible universe. Formed in the big bang or in cataclysmic astrophysical explosions, atomic nuclei are a crucial and intriguing part of the world. The basic features of atomic nuclei were understood in terms of the nuclear shell model in the 1963 Nobel Prize winning research of Eugene Paul Wigner, Maria Goeppert-Mayer, and J. Hans de Jensen. Since then, exte...

Low Energy Nuclear Reactions

Character and Role of Theory Storms’ view of where and how low energy nuclear reactions (LENR) occur has been called a theory, so we begin with an examination of the character of a scientific theory. A compact summary about theory in any science is available in Wikipedia: “A scientific theory is a well-substantiated explanation of some aspect of the natural world, based on a body of facts that ...
