Question

If an atom is placed instead of electron in compton experiment what would happen?

Answer 1

There are several possible variants:
1) photon will hit with electron and
will give all it's energy to electron(w=hf);
2) photon will hit with
electron and will not give all it's energy to electron, because it's energy
is smaller than difference between next
possible and current energy levels of
electron;
3) photon will give all it's impulse atomic nucleus;
4) it will
not interact with atom;
