抄録

Angular distributions of inelastically scattered alpha-particles, leading to the ΔT=0 spin-flip states of C12 at 12.7 MeV and B11 at 8.6 MeV, were observed. These angular distributions were found to show a unique pattern. Such characteristic of the angular distributions were also observed for the 10.4 MeV state of Mg24 and the 8.9 MeV state of Si28. These four states were systematically interpreted as the ΔT=0 spin-flip states by the j-j coupling shell model.<BR>The excitation mechanism for these states is discussed and it is concluded that a spin-orbit interaction between the incident alpha-particle and a nucleon in the target nucleus plays an important role.<BR>The angular distribution for another unnatural-parity state of C12 at 11.8 MeV (2), Mg24 at 5.22 MeV(3+) and Si28 at 6.27 (3+) were also observed.<BR>The 14.08 MeV collective state of C12 was found to be excited strongly.
