Atomic Nuclear Physics

The quantum quark by Andrew Watson

By Andrew Watson

Quantum chromodynamics (QCD), the speculation explaining the powerful nuclear strength that binds jointly the parts of the atomic nucleus, is likely one of the 4 primary forces of nature that keep an eye on the universe during which we are living. This soaking up booklet covers the tips and tales in the back of QCD, the successes and the puzzles, the unsolved mysteries and the characters concerned. the topic is mentioned in an available and unique means, assuming purely the minimal physics and arithmetic heritage wisdom. it's a interesting learn for someone drawn to technological know-how and a fantastic advent for college students embarking on particle physics classes

Quantum optics: quantum theories of spontaneous emission

The aim of this text is to check spontaneous emission from numerous assorted viewpoints, even supposing a wide a part of will probably be dedicated to the quantum statistical theories of spontaneous emission which were constructed lately, and to discussing the interrelations between varied ways.
