1.
Discrete alpha energies show that...
alpha particles are photons
nuclei are always stable
the nucleus has discrete energy levels
protons have no mass
2.
The energy of a gamma photon equals...
the difference between two nuclear energy levels
the total mass of the nucleus
the proton rest energy
half the binding energy
3.
Typical nuclear gamma photon energies are of order...
eV
GeV
μeV
keV to MeV
4.
A nucleus emits a 0.60 MeV photon in a transition to the ground state. The initial level energy is...
0.30 MeV above ground
0.60 MeV above ground
1.20 MeV above ground
0.60 MeV below ground
5.
Why is the beta energy spectrum continuous but the alpha spectrum discrete?
Alpha decay has no energy
Beta has no charge
Alpha is a photon
Beta decay involves three bodies sharing energy
6.
A nucleus has levels at 0, 0.4 and 1.0 MeV. How many different photon energies can be emitted from the 1.0 MeV level?
