Cluster structure in A=6 nuclei above particle decay threshold

ORAL

Abstract

The di-trinucleon clustering-resonance of $^{3}$He+$^{3}$He in $^{6}$Be and t+t in $^{6}$He were studied via the $^{6}$Li($^{3}$He,t $^{3}$He) and $^{6}$Li($^{7}$Li,$^{7}$Be t) reactions at the incident energies of 150 MeV/A and 65 MeV/A. A new resonance in $^{6}$Be and $^{6}$He was found at around Ex=18 MeV in the binary decay channel of $^{3}$He+$^{3}$He and t+t. The angular correlations measured for $^{3}$He and t particles in the binary decay show a contribution dominantly from the multipolarity of an L=1.
