Definition
C1Nuclear Physics
(technical, academic)A process where an excited atomic nucleus releases excess energy by emitting high-energy electromagnetic radiation known as gamma rays.
Example
- Gamma decay often follows alpha or beta decay, releasing energy without changing the number of protons or neutrons in the nucleus.
- The high penetration depth of gamma rays emitted during gamma decay makes them useful in medical imaging.
C2Finance
(technical)A measure of the rate of change of gamma, which itself is the rate of change of an option's delta, with respect to time or changes in the underlying asset price.
Example
- Traders monitor gamma decay to understand the changing sensitivity of an option's delta over time.
