Introduction
What is Nuclear Physics ?
It is the study of the phenomena of the atomic nucleus
Understand:
composition - what is it made of?
properties - size, mass, charge, angular momentum
structure - do nuclei have internal structure?
interactions - how do nuclei interact with everything else?
decays - how and why do some nuclei decay
!

Introduction
Why Study Nuclear Physics ?
Plays an important part in our lives Nuclear Fission : Source of energy from reactors / weapons Nuclear Fusion : Maintains (nearly) all life Creation of all the heavy elements – Nucleosynthesis Possible future source of low pollution energy Radioactive Decay: carbon dating, smoke alarms Isotope Abundances: isotope ratios
paleoclimate temp. proxies !
Medical Applications: Diagnostic Uses Imaging Therapeutic uses for cancer treatment
An understanding of nuclear physics will enable you to make an informed contribution to the debate on the the use of nuclear materials and science and to understand their limitations and their benefits

Introduction
What We Know About Nuclear Physics
• Early Nuclear Experiments (How we know what we know!)
Nuclear Sizes (scales, ranges)
Application of Quantum Mechanics to Nuclear Phenomena
• Nuclear Forces (magnitude of the forces, mechanisms) • Nuclear Models (A very brief introduction to the types)
Borrow ideas from atomic physics !
nucleus is a complex quantum system
! !
exact calculations not really possible use several simplified models to describe different phenomena

History of Nuclear Physics
1895 The discovery of X-rays by Wilhelm Röntgen ! from discharge tubes & fluorescent plates
1931 Pauli theory of the neutrino in beta decay
1896 Henri Becquerel investigated fluorescence in ! uranium salts. His photographic plates were fully exposed before coming close to discharge tubes: discovery of radioactivity
1932 discovery of the neutron – Chadwick
1897 Investigations into radioactivity in radium by ! Marie & Pierre Curie. First woman to win Nobel! Prize
1934 Fission observed – Fermi / Hahn 1941 Start of the Manhattan Project 1942 First Reactor – Fermi
1911 Discovery of the atomic nucleus by Rutherford
1945 The Atomic Bomb, Oppenheimer
1913 Bohr model of atom
1948 Nucleo-synthesis – Bethe, Gamow
1914 Determination of nuclear charge
1952 Hydrogen Bomb
1919 Rutherford discovers the proton by producing ! hydrogen from alpha bombardment of Nitrogen

Scales in Nuclear Physics
Sizes Everyday Matter ~1m
Typical Energies 0.01 eV - thermal energies
Molecule 10-9 m
1 eV - binding energy of molecule
Atom 10-10 m
10 eV – 1keV
Nucleus 10-14 m
1 MeV – 10 MeV
Proton 10-15 m
1 GeV
Nucleus is 4 orders of magnitude smaller than atom Dr Eram Rizvi

Binding Energy
Nuclear mass MN less than sum of nucleon masses Shows nucleus is a bound (lower energy) state for this configuration of nucleons Leads to concept of binding energy B of a nucleus
MN (A, Z)c2 = Zmp c2 + (A
Z)mn c2
B
mp = proton mass mn = neutron mass
Binding energy: Energy required to separate nucleus into component parts
Binding energy of average nucleon is ~ 8 MeV significant compared to nucleon mass itself!

Binding Energy Binding Energy Per Nucleon
The nuclear binding energy allows us to explain and investigate many nuclear properties e.g. fission, fusion and models of nuclear forces
Dr Eram Rizvi
We will attempt to understand this curve using the Semi-empirical mass formula (future lecture)
