I'm up to speed on the physics behind fusion and fission, what I am missing is this fractional fusion/fission idea with respect to quarks.

The suggestion was (as I understand it) that one could "inject/collide/drop" a neutron onto this matter and the neutron would then fission into it's component quarks, capturing them and releasing the binding energy. So this stable matter is a quark soup held together by the strong force because you've managed to get enough up and down quarks together at a low enough energy?

It isn't a mechanism I'm familiar with and I was interested if there was any experimental results to suggest this stuff would behave the way they hope it would.
