Description
Cluster degree of freedom of neutron rich nuclei with heavier cluster core like O isotope gets much attention. We propose studies of cluster degree of freedom in neutron-rich 28Ne and 32Mg via inelastic scattering on liquid He target, which is useful to excite cluster energy level. Invariant mass spectroscopy of 24O + (28Ne), 24O + 2 and 28Ne+ (32Mg) decay channels is performed in order to reconstruct cluster energy levels which appear above emission threshold (S). This method was successfully utilized with SAMURAI for cluster degree of freedom in 16C (NP1112-SAMURAI08). The setup of the experiment is nearly the same as NP1112-SAMURAI08, except that PDCs are placed to obtain A=Z = 2 particles with sufficient angular covorage as well as appropriately high efficiency for Z = 2 particles. Other decay channels of symmetric break-up as the 32Mg -> xC + xC + xn reactions are expected to be measured simultaneously by the property of large acceptance of SAMURAI.
