Scientists at Tokyo Institute of Technology have extended an existing mathematical model so that it can be used to more accurately predict the products of fission reactions.  The nuclear force that holds protons and neutrons together in the center of atoms has a non-central component—the tensor force, which depends on the spin and relative position of the interacting particles.  Physicists at the TU Darmstadt and their collaboration partners have performed laser spectroscopy on cadmium isotopes to confirm an improved model of the atomic nucleus.  Protons in neutron-rich nuclei have a higher average energy than previously thought, according to a new analysis of electron scattering data that was first collected in 2004.
