Consider a neutron as consisting of a proton plus a π- meson in
an l = 1 orbital state. What would be the orbital magnetic dipole
moment of such a configuration? Express your resultas a multiple of
the proton’s magnetic moment.
How would you determine the number of proton-proton pairs, the
number of neutron-neutron pairs, and the number of neutron-neutron
pairs in an atom given its atomic number and mass number? Hence
show that Carbon has 15 proton-proton pairs and 10 neutron-neutron
pairs.
Differences? They are both an electron and a proton, since the
neutron decays to a proton and an electron, what's the difference
between a neutron and proton + electron? so is it just a higher
binding energy between the two?
If you drop a proton and a neutron in a gravitational field,
they both fall, but the proton has a charge and accelerating
charges radiate energy, so that leaves less kinetic energy for the
proton and by this reasoning, it should fall more slowly than a
charge-free object.
The issue is discussed but not in the terms above in Peierls's
"Surprises in Theoretical Physics" in the chapter "radiation in
hyperbolic motion", but I didn't understand the chapter well enough

The proton mass is 1.007276 amu , the neutron mass is 1.008665
amu , and the electron mass is 5.486×10−4 amu .
What is the expected mass of a potassium-39 nucleus, based on

The actual measured mass of a potassium-39 atom is 38.963707 amu

(a) You decided to turn a neutron into a proton. Making sure
that the charge is conserved, you wrote down n → p + e-.
When you actually did the experiment, an antineutrino came out in
addition, making the actual interaction n → p + e -+ ¯ν.
Among what needs to be conserved, what was not conserved in the
interaction without the antineutrino?
(b) You managed to capture the emitted electron inside of a
one-dimensional infinite potential well with...
Outside the nucleus, the neutron itself is radioactive and
decays into a proton, an electron, and an antineutrino. The
half-life of a neutron (mass = 1.675 × 10-27 kg) outside the
nucleus is 10.4 min. On average, over what distance x would a beam
of 5.55-eV neutrons travel before the number of neutrons decreased
to 75.0% of its initial value? Ignore relativistic effects.
The deuteron is a bound state of a proton and a
neutron of total angular momentum j = 1. It is known to be
principally an S(ℓ = 0) state with a small admixture of a D(ℓ = 2)
state. Calculate the magnetic moment of the pure d state n-p system
with j = 1. Assume that the n and p spins are to be coupled to make
the total spin s which is then coupled to the orbital angular...

Express your answer numerically in joules per mole.
Please solve this conceptual question.
In positron decay, a proton in the nucleus becomes a neutron and
its positive charge is carried away by the positron. A neutron,
though, has a larger rest energy than a proton. How is that
possible?
