31.1 Exercise 1

Avg difficulty 2.5

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

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