Gamow's Theory of Alpha Decay AND Geiger Nuttal Law

Gamow's Theory of Alpha Decay gives and explanation as to how an alpha particle escapes the potential barrier of a nuclei even though its Kinetic Energy is less than the maximum potential height. Its is a very interesting thing that vast majority of alpha particles have a maximum energy of around 4-9 MeV while the nuclear potentials of such nuclear species have a maximum of height of around 25MeV. How is it possible that such an alpha particle having kinetic energy 16-21 MeV less than the barrier potential still manages to escape from it. This is not allowed in Classical Physics. However, it is possible in Quantum Physics. Small particles having energy less than the barrier potential have a small but finite probability of 'tunneling' through that barrier. This is known as Quantum Tunneling. George Gamow applied this concept of Quantum Tunneling to explain the above puzzle related to Alpha Decay. One prediction of this theory is how two different alpha particles having different Kinetic Energies will show different barrier. Since tunneling probability depends on the width of the barrier, two different alpha particles having different Kinetic energies will experience two different 'effective' barriers. This will result in the fact that the half lives of both nuclear species will be different. As it turns out, the half life of a nuclear species that emits a high energetic alpha particle is less than the half life of a nuclear species that emits a low energetic alpha particle. This is the essence of Geiger Nuttal law, which has experimental validation. ▱▱▱▱▱▱▱▱▱▱▱▱▱▱▱▱▱▱▱ Support💖  / dibyajyotidas   Donate🤝🏻https://paypal.me/FortheLoveofPhysics Telegram - https://t.me/FortheLoveofPhysicsYT ▱▱▱▱▱▱▱▱▱▱▱▱▱▱▱▱▱▱▱ Follow my other videos here... •••••••••••••••••••••••••••••••••••••••••• NUCLEAR AND PARTICLE PHYSICS - Series : •••••••••••••••••••••••••••••••••••••••••• 1) What is Nuclear Physics? ►    • What is Nuclear Physics? (LECTURE SERIES)   2) Nuclear Size / Radius ►    • Nuclear Size / Radius   3) Quantization of Angular Momentum ►    • What is Quantization of Angular Momentum? ...   4) Nuclear Spin and Angular Momentum ►    • Nuclear Spin and Angular Momentum   5) Nuclear Magnetic Moment ►    • Nuclear Magnetic Moment   6) Binding Energy of Nucleus & BE Curve ►    • What is Nuclear Binding Energy? (and BE pe...   7) Parity of Wave function ►    • What is Parity of a Wave function? (Odd / ...   8) Symmetric & Anti symmetric Wave func ►    • Symmetric and Anti-symmetric Wave functions   9) Liquid Drop Model of Nucleus ►    • Liquid Drop Model of Nucleus ( Binding Ene...   10) Corrections to Liquid Drop Model ►    • Corrections to Liquid Drop Model / Semi Em...   11) NZ Graph (& Maximizing BE) ►    • What is NZ Graph? | Maximizing Binding Energy   12) Fermi Energy of Nucleus ►    • Fermi Energy of Nucleus (Derivation)   13) Fermi Gas Model of Nucleus ►    • Fermi Gas Model of Nucleus   14) Shell Model of Nucleus ►    • Shell Model of Nucleus   15) Nature of (Strong) Nuclear Force) ►    • Nature of (Strong) Nuclear Force   16) Alpha, Beta & Gamma Decay ►    • Alpha, Beta & Gamma Decay [Complete Discus...   17) Gamow's Theory of Alpha Decay ►    • Gamow's Theory of Alpha Decay AND Geiger N...   18) Gamow's Theory (DERIVATION) ►    • [DERIVATION ] Gamow's Theory of Alpha Decay   19) Q Value and KE of Alpha Decay ►    • Q-Value | KE of Alpha Decay (Kinematics)   20) Beta Decay & Neutrino Hypothesis ►    • Beta Decay & Neutrino Hypothesis !! (VIOLA...   21) Radioactive Decay Law ►    • What is Radioactive Decay? Half Life | Dec...   22) Nuclear Cross Section ►    • Nuclear Cross Section Explained   23) Interaction of Nuclear Radiation with Matter ►    • Interaction of Nuclear Radiation with Matter   24) What is Cherenkov Radiaton? ►    • Cherenkov Radiation Explained Simply   25) Nuclear Detectors ►    • Nuclear Detectors - Ionization Chamber & P...   26) Geiger Muller Counter ►    • What is GM Counter? - Geiger Muller Counter   27) Scintillation Detector ►    • What is a Scintillation Detector? Explained   28) Semiconductor Detectors ►    • What are Semiconductor Detectors?   29) What are Accelerators? ►    • What are Accelerators? + Electrostatic Par...   30) Van de Graaff Generator ►    • Van de Graaff | Tandem & Pelletron Particl...   31) Linear Accelerator ►    • Linear Particle Accelerator (Principle, Co...   32) Cyclotron ►    • Cyclotron (Principle, Construction, Workin...   33) Synchrotron ►    • Cyclotron & Synchrotron (Particle Accelera...   34) Betatron ►    • Cyclotron & Synchrotron (Particle Accelera...   35) Fission & Fusion ►    • Nuclear Fission and Fusion | What role doe...   36) Proton-Proton & CNO Cycle ►    • Proton Proton Cycle & CNO Cycle   37) Meson Theory of Nuclear Forces ►    • Meson Theory of Nuclear Forces & Estimatio...   ••••••••••••••••••••••••••••••••••••••••••• NUCLEAR PHYSICS - PLAYLIST    • Nuclear Physics   ••••••••••••••••••••••••••••••••••••••••••• #NuclearPhysics
