As soon as they come to rest, they combine with an electron to form two -ray photons in a matter-antimatter annihilation reaction.-decay are often obtained in an excited state.

The excess energy associated with this excited state is released when the nucleus emits a photon in the -ray portion of the electromagnetic spectrum.

Nuclear physics is important in a vast variety of situations, from understanding how the Sun provides the energy for life on this planet, to nuclear power plants and radiation therapy.

Without nuclei, we simply would not exist, and it is important to understand why!

NTI and its partners, Creative Santa Fe and the NSquare Collaborative, have won the 2017 Most Significant Futures Work Award for “analyzing a significant future issue” for the 2016 Disruptive Futures: Santa ...

En 1996 nous avons publié les résultats d’une étude de cristaux d’or faux et authentiques de la mine d’or de Santa Elena, au Venezuela, et nous avons montré que la méthode de datation U/Th – He est un outil puissant pour détecter les contrefaçons dans le cas des objets en or.U and Th decay by emitting He atoms that remain stored in gold.By measuring U, Th, and He, the time when the He trapping process started can be determined.Materials as young as tens of years and older than 600,000 years are potentially dateable by the Dorale J. Nuclear Physics is the study of the properties and behaviour of nuclei and particles, ranging from tiny quarks to giant explosions deep in space.

La décroissance de l’U et du Th se fait par émission d’atomes d’He qui restent stockés dans l’or.
