Restoring the valence-shell stabilization in 140Nd

A nuclear-structure paper on restoring valence-shell stabilization in ¹⁴⁰Nd, the N=80 isotone where proton-neutron pairing should quiet collectivity.

Coulomb-excitation and complementary spectroscopy of ¹⁴⁰Nd, published as a Physical Review C rapid communication. Transition strengths show whether the valence shell is behaving as a closed, stabilized system.

If stabilization returns in ¹⁴⁰Nd, the isovector search in the neighbouring Nd/Sm conference paper has a quieter core to excite. The two records are the same N=80 question from two observables.
