Webremoves loosely bound outer shell electrons and ionizes the atom;x-ray continues in a different direction with less energy;within the diagnostic range. what is the ejected electron called in compton effect. compton electron or secondary electron. the energy of a _______x-ray is equal to the difference between the _____ of the incident x-ray and ... WebBoth pair production and photodisintegration are endothermic (energy-absorbing) processes, and, thus, tend to cause the star to collapse. However, their eventual effects on the collapsing star are different; pair production causes only a partial collapse, followed by runaway thermonuclear fusion and a supernova explosion, while ...
