16Oxygen is well-characterized using a variety of ab initio nuclear many-body strategies, partly because it is doubly magic and has an equal number of protons and neutrons. Even though 28O is doubly magic, the unequal number of protons and neutrons creates computational difficulties for even ground-state computations, never mind decays.
