I haven't looked at it very carefully, but I think the island of stability is not in a nuclear "s" state - meaning a spherically symmetric nucleus with zero angular momentum apart from spin.

It's in a p, d or f state, meaning that the nucleus is shaped like a donut or oblate spheroid, and it's rotating fast enough to keep itself in that shape.

That pulls the nucleons away from each other so the nucleon density is lower. That's probably what prevents the neutron loss.

I think I have an inkling of how atoms like that might interact with gravity as well.

Eugene Podkletnov demonstrated antigravity using a disk-shaped spinning ceramic superconductor, pulsing electricity radially through it as it spins.

Objects situated above the disk became lighter, exhibiting less attraction to the earth.

Martin Tajmar replicated this after various failed attempts. He found that the superconductor must be type 1 (magnetic flux cannot penetrate it by forming non-superconducting channels). Niobium was the most effective superconductor he found.

These experiments create a spiral or vortex of electric current. It seems that electomagnetic vortices couple to the gravitational field.

The famous "die Glocke" experiment was probably trying to achieve the same effect using superconducting mercury (a type 1 superconductor available at the time).

Anyway, if you have these rotating donut-shaped nuclei, they're effectively tiny circular superconducting circuits.

You could use an external magnetic field to make them all orient themselves in the same direction.

Then if you bombard them with something, they will wobble as their nuclear orbital state mixes and sloshes between p, d, and f states with angular momentum pointing in various different directions at various times.

So the donut's radius can be affected, and the circulating current won't be just going in a circle, but something between a circle and a spiral.

So there will be a little bit of an electromagnetic vortex formed within each atom, and if you have all these vortices swirling coherently and pointing in the same direction, then it should generate a gravitational impulse.

So that's how you would use a substance like that for antigravity propulsion.
