WebNuclear fusion sequence and silicon photodisintegration. After a star completes the oxygen-burning process, its core is composed primarily of silicon and sulfur. If it has sufficiently high mass, it further contracts until its core reaches temperatures in the range of 2.7–3.5 GK (230–300 keV).At these temperatures, silicon and other elements can photodisintegrate, … Web中国两弹之父是谁-邓稼先1929年邓稼先9月入北平武定侯小学，至3年级。1932年邓档扒稼先入北平四存小学四年级，至毕业。1935年邓稼先11岁，入北平志成中学，读一年级。1936年邓稼先12岁，插班考入北平崇德中学初...
Photodisintegration (also called phototransmutation, or a photonuclear reaction) is a nuclear process in which an atomic nucleus absorbs a high-energy gamma ray, enters an excited state, and immediately decays by emitting a subatomic particle. The incoming gamma ray effectively knocks one or more … See more A photon carrying 2.22 MeV or more energy can photodisintegrate an atom of deuterium: 1D + γ → 1H + n James Chadwick and Maurice Goldhaber used this reaction to … See more A photon carrying 1.67 MeV or more energy can photodisintegrate an atom of beryllium-9 (100% of natural beryllium, its only stable isotope): See more Terrestrial lightnings produce high-speed electrons that create bursts of gamma-rays as bremsstrahlung.
