Hi.

This may be a trivial question, but I'm unable to find a definitve answer.

How is the mass on a atomic nucleus distributed?

I read somewhere that it was uniformly distributed, and somewhere else that it resembled a normal distribution. Can you help me out?

Thank you.

Above may help. Short answer - models are approximate.

And according to the most correct model how is the mass distribution like?

Nuclear mass distribution

Roughly uniform in the center, and then relatively sharp edges. Apart from halo nuclei, but they are exotic and not long-living.

And of course many nuclei are ellipsoidal rather than spherical.

If you use a harmonic oscillator potential, then the single-particle wavefunctions will resemble Gaussian shapes (like a normal distribution). But that's an unrealistic feature of the harmonic oscillator potential.
