Is it viable to convert nuclear waste into safe isotopes?
I read that powerful pulsed lasers can change isotopes:
J. Magill, et. al.: "Laser transmutation of iodine-129".
Did anyone estimate what would be the energy costs to transmutate 1 kg of fission ...

Why some nuclei with “magic” numbers of neutrons have a half-life less than their neighbor isotopes?
It's easy to find the "magic" numbers of neutrons on the diagrams of alpha-decay energy: 82, 126, 152, 162. Such "magic" nuclei should be more stable than their neighbors.
But why some nuclei ...

Obtaining isotope stability
For a given isotope, one can obtain the binding energy using the semi-empirical mass formula.
For example, has a binding energy of 1782.8 MeV. From this information, how can the likelihood of the ...
