What is Gamma Decay?

Gamma decay is an electromagnetic transition between nuclear energy levels, resulting in the emission of high-energy photons (gamma rays) or internal conversion electrons.

Transition Types

Key characteristics:

• Electric transitions (E1, E2, E3...)
• Magnetic transitions (M1, M2, M3...)
• Selection rules based on spin/parity
• Transition probabilities

Internal Conversion

Alternative process where:

• Nuclear energy transfers to electron
• Electron ejection occurs
• Atomic reorganization follows
• X-ray or Auger emission

Selection Rules

Transitions must follow:

• Angular momentum conservation
• Parity conservation
• Energy conservation
• Electromagnetic multipole rules

Applications

Gamma decay is important in:

• Nuclear spectroscopy
• Medical imaging
• Material analysis
• Nuclear structure studies
