Single-particle decomposition of nuclear surface diffuseness

Understand

Nuclear surface diffuseness reflects spectroscopic information near the Fermi level.

• I propose a way to decompose the surface diffuseness into single-particle (s.p.) contributions in a quantitative way.
• Systematic behavior of the surface diffuseness of neutron-rich even-even O, Ca, Ni, Sn, and Pb isotopes is analyzed with a phenomenological mean-field approach.
• The role of the s.p.
