31.1 Exercise 1

A nucleus is observed to emit a $\gamma$ ray with a frequency of $6.3 \times 10^{19} \textrm{ }\text{Hz}.$ What must happen to the nucleus as a consequence?

The nucleus must gain 0.26 MeV.
The nucleus must also emit an α particle of energy 0.26 MeV in the opposite direction.
The nucleus must lose 0.26 MeV.
The nucleus must also emit a β particle of energy 0.26 MeV in the opposite direction.
