Abstract :

We have performed reaction cross section (�?R) measurements to deduce the matter density distribution of 14Be. We deduced the matter density distribution of 14Be from the measured �?R of 14Be with both proton and carbon targets at around 41 and 76MeV/nucleon and previously measured �?R 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.
