Why are α- and β-particle emissions often accompanied by γ-rays? |
|
Answer» A given nucleus does not emit α- and βparticles simultaneously. However, on emission of α or β-particles, most nuclei are left in an excited state. A nucleus in an excited state emits a γ-ray photon in a transition to the lower energy state. Hence, α- and βparticle emissions are often accompanied by γ-rays. |
