Questions and Answers
What is the characteristic of beta rays emitted by some nuclei?
They are emitted with a continuous spectrum of energies up to a maximum (E_{max})
What happens when a positive beta particle comes to the end of its range?
It combines with a nearby negative electron, neutralizing each other and converting their combined masses into energy
What is internal conversion in radioactive decay?
Gamma rays emitted by some nuclei do not leave the atom, but are photoelectrically absorbed in its K shell, resulting in emission of photoelectrons and characteristic x-rays
