在扭曲波冲量近似（DWIA）框架下研究了392 MeV的反应.结果表明，该反应是非常外围的，主要是由于反应残留物对~（12）的强烈吸收，并且可以清楚地探测到核表面的成簇现象。我们还调查了迄今为止经常使用的所谓的因式分解近似的有效性。结果表明，核内区的畸变对反应的运动学有显著的影响，但对反应的可观测量没有影响，这是因为核内区有很强的吸收.
Thereaction at 392 MeV is investigated with the distorted wave impulse approximation (DWIA) framework. We show that this reaction is very peripheral, mainly because of the strong absorption ofby the reaction residue, and theclustering on the nuclear surface can be probed clearly. We investigate also the validity of the so-called factorization approximation that has frequently been used so far. It is shown that the kinematics ofin the nuclear interior region is significantly affected by the distortion of, but it has no effect on the reaction observables because of the strong absorption in that region.
