When a nucleus undergiv i+x*lk 59izoes eithwvl /x w0 .g43kxs1qg.,eioum er $\beta^-$ or $\beta^+$ decay, what happens to the energy levels of the atomic electrons? What is likely to happen to these electrons following the decay?
参考答案:
With
$\beta^-$ or $\beta^+$ decay, the number of protons in the nucleus changes. In $\beta^-$ decay, the number of
protons increases, and in $\beta^+$ decay, the number of protons decreases. Thus, the charge of the nucleus changes and
when this occurs all of the energy levels of the atomic electrons change in
size. Recall that both the energy values
of the level and the Bohr radii are dependent on Z (the charge of the
nucleus). Thus, after the decay, there
is a lot of shuffling around of the electrons into the new and different energy
levels. The electrons will change
energies to occupy the new energy levels, and so many photons corresponding to
those energy level changes will be emitted.
