|We have performed reaction cross section (σR) measurements to deduce the matter density distribution of 14Be. We deduced the matter density distribution of 14Be from the measured σR of 14Be with both proton and carbon targets at around 41 and 76MeV/nucleon and previously measured σR at relativistic energies. 14Be (Z=4, N=10) nucleus is thought to be the two-neutron halo nucleus consisting a core nucleus 12Be plus the two valence neutrons. Our observation supports this picture. Furthermore, the resultant density distribution is found to have dominant configuration of the s-wave with partial mixture of the d- or p-wave. In our analysis, 39% mixing of the p-wave is suggested. We also compared the deduced root-mean-square matter radius with the theoretical calculations. The detail of the comparison will be presented.|
Tetsuaki Moriguchi has completed his PhD from University of Tsukuba. His interests are density distributions and radii of unstable nuclei located far from stability line on the nuclear chart.
