Nuclear Physics and RadioactivityEasy
Question
A photon of 1.7 × 10-13 Joules is absorbed by a material under special circumstances. The correct statement is :-
Options
A.Electrons of the atom of absorbed material will go the higher energy states
B.Electron and positron pair will be created
C.Only positron will be produced
D.Photoelectric effect will occur and electron will be produced
Solution
Energy = 1.7 × 10-13 J
=
MeV = 1.0625 MeV
⇒ Pair production will take place
=
MeV = 1.0625 MeV⇒ Pair production will take place
