2 Outline WHAT are we measuring? - Nuclear/atomic masses WHY do we need/want to measure it? - Precision requirements - Physics motivation HOW do we measure it? - Precision measurement techniques
3 WHAT The Mass of an Atom What is the mass of an atom with Z protons and electrons and N neutrons? protons neutrons electrons
4 The Mass of an Atom What is the mass of an atom with Z protons and electrons and N neutrons? protons neutrons electrons Need to account for the binding energy
5 The Mass of an Atom What is the mass of an atom with Z protons and electrons and N neutrons? protons neutrons electrons Need to account for the binding energy What is the binding energy of a nucleus?
6 Binding Energy of Stable Nuclei Answer: It depends on the nucleus! Binding energy 8 MeV/N (~1% of the atom s mass) Binding energy and therefore atomic mass is a unique, fundamental property of a nucleus
7 Binding Energy of Stable Nuclei Answer: It depends on the nucleus! Binding energy 8 MeV/N (~1% of the atom s mass) Nuclear masses can tell us something about nuclear structure and forces. Binding energy and therefore atomic mass is a unique, fundamental property of a nucleus Nuclear masses are needed as inputs for understanding physical processes
8 WHAT Unified Atomic Mass Unit The atomic mass unit is defined as 1/12 th of the mass of 12 C in its ground state 1 u = m u = 1 12 m( 12 C )
9 WHAT Unified Atomic Mass Unit The atomic mass unit is defined as 1/12 th of the mass of 12 C in its ground state 1 u = m u = 1 12 m( 12 C ) (not amu, please)
10 WHAT Unified Atomic Mass Unit The atomic mass unit is defined as 1/12 th of the mass of 12 C in its ground state 1 u = m u = 1 12 m( 12 C ) Conversion to kev 1 u = 931, kev 1 u m p m n 1 GeV Mass Excess ME = Δ = M[ A X] A 931, kev/u in u a number
