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