Shape Coexistence in 68Ni and surrounding neutron-rich nuclei

The structure of neutron-rich nuclei in the vicinity of “doubly-magic” 68Ni has been the subject of much recent scrutiny once it was realized, on the one hand, that the subshell gap at neutron numb

The Difference a Pair of Neutrons Can Make

Add barium-146 to the short list of pear-shaped nuclei, though this may be more surprising than one might expect given the pear-shaped nature of its nearby neighbor barium-144.

Microscopic calculations for neutrino scattering from nuclei

Although neutrinos were postulated in 1930 and first observed in 1956, the fact that they are not massless was only demonstrated in the 1990's the values of their masses is still unknown.
