Shell model structures of low-lying excited states in6,7Li

Electron and intermediate energy proton scattering data from ${}^6$Li and ${}^7$Li, both elastic and inelastic, have been analyzed using wave functions obtained from shell model calculations involving spaces ranging from the conventional $0ħ\omega$ space to the $\mathrm{}(0+2+4)\mathrm{}ħ\omega$ one. The results, along with those of the static and dynamic properties of the low-lying spectra of the nuclei, allow for a strict assessment of the wave functions, as well as giving an indication of possible clusterlike behavior in those systems.
