| Abstract | Two low-lying unbound states in C-16 are investigated by deuteron inelastic scattering in inverse kinematics. Besides the 2(-) state at 5.45 MeV previously measured in a 1n knockout reaction, a new resonant state at 6.89 MeV is observed for the first time. The inelastic scattering angular distributions of these two states are well reproduced by the distorted-wave Born approximation (DWBA) calculation with an l = 1 excitation. In addition, the spinparities of the unbound states are discussed and tentatively assigned based on shell model calculations using the modified YSOX interaction. |
