Who found an empirical relationship between the half-life of alpha decay and the
energy of the emitted alpha particles in 1911?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Geiger and Nuttall i.e.
- Already in 1911, Geiger and Nuttall developed the first empirical formula for determining the alpha decay half-lives.
- In 1928, the first useful theoretical model of the alpha decay as a pure quantum tunneling effect was published by Gamow, Condon and Gurney.
- Geiger's law: It is the semi-empirical law that expresses the lifetime of the half-life of the alpha emitter in terms of the energy of the released alpha particle.
