Question

In Compton scattering
a) The modified line occurs because of scattering with a single electron
b) The unmodified line occurs because of scattering with the entire atom
c)The electron can recoil at an angle greater that ${90}^o$ .
d) The scattering photon and recoil electron can be projected on the same side of the incident direction

• A. a, b, c
• B. a, b, d
• C. b, c
• D. a,b

Answer 1

The correct option is A a, b, c

The modified line occurs due to collision of photon with single electron.
Compton scattering usually refers to the interactive involving only the electrons of atoms,if photon does not collide with any of electron of an atom, then it shows unmodified lines.
