From cluster structures to nuclear molecules: The role of nodal structure of the single-particle wave functions


Author(s): A. V. Afanasjev and H. Abusara

The nodal structure of the density distributions of the single-particle states occupied in rod-shaped, hyper- and megadeformed structures of nonrotating and rotating $N∼Z$ nuclei has been investigated in detail. The single-particle states with the Nilsson quantum numbers of the $[NN0]1/2$ (with $N$ ...

Structures of low-lying $0s$-orbit $\mathrm{Λ}$ states in $p$-shell $\mathrm{Λ}$ hypernuclei ($_{\mathrm{Λ}}^{A}Z$) are investigated by applying microscopic cluster models for nuclear structure and a single-channel folding potential model for a $\mathrm{Λ}$ particle.
