如果放射性衰變出alpha粒子後，伽傌射線會在何時才被核子釋出?
伽傌射線的釋出是否因為核衰變後的質量虧損所引致?
其實整個衰變的過程是怎樣的?
During the process in radioacative decay, when will the gamma-ray be emitted after an alpha/beta particle be emitted?
Is that the mass defect causes gamma-rays be emitted?
What is the detailed process in a radioactive decay?

✔ 最佳答案
After an alpha or a beta decay, if the daughter nuclide is left in an excired state, then gamma rays will be produced when the daughter nuclide de-excites itself by falling into the ground state.Hence, the emission of gamma rays is not caused by mass defect. It is because of difference in energy levels of the daughter nuclides.
