Electric-dipole transitions in ${}^6$Li with a fully microscopic six-body calculation

Abstract

Exploring new excitation modes and the role of the nuclear clustering has been of great interest. An interesting speculation was made in the recent photoabsorption measurement of ${}^6$Li that implied the importance of the nuclear clustering. To understand the excitation mechanism of ${}^6$Li, we perform a fully microscopic six-body calculation on the electric-dipole ($E1$) transitions and discuss how ${}^6$Li is excited by the $E1$ field as a function of the excitation energy. We show the various cluster components in the six-body wave functions and discuss the role of the nuclear clustering in the $E1$ excitations of ${}^6$Li.
