The material particle nature of primary cosmic radiation has been confirmed, although the processes turned out to be extraordinarily more complicated than we had assumed.
Walther BotheMany applications of the coincidence method will therefore be found in the large field of nuclear physics, and we can say without exaggeration that the method is one of the essential tools of the modern nuclear physicist.
Walther BotheTo demonstrate this simultaneity is by no means trivial, because it may for example happen that the product nucleus always forms in an activated state at first.
Walther BotheIn this case, the particle formed has correspondingly less energy, whereas the product nucleus passes into the ground state with emission of the quantity of energy saved as gamma radiation.
