用连续离散耦合道理论（弹性破裂过程）和Glauber模型（核子剥离过程）分析了氘在{sup 7}Li上破裂反应的核子包容谱。这两个理论模型都使用了相同的唯象核子光学势，并且没有其他的自由参数。计算再现以及观察到的一个突出的凸点约一半的入射能量在实验包括40 MeV（d，xn）和100 MeV（d，xp）的反应在前进角的光谱。分析表明，在氘在{sup 7}Li上的碎裂反应中，剥离过程比弹性碎裂过程更重要。
Inclusive nucleon spectra from deuteron breakup reactions on {sup 7}Li are analyzed in terms of the continuum discretized coupled channels theory for the elastic breakup process and the Glauber model for the nucleon stripping process. Both theoretical models use the same phenomenological nucleon optical potential of {sup 7}Li and have no other free parameters. The calculations reproduce well a prominent bump observed around half the incident energy in experimental inclusive spectra of 40-MeV (d,xn) and 100-MeV (d,xp) reactions at forward angles. The analysis shows that the stripping process is more important than the elastic breakup process in deuteron breakup reactions on {sup 7}Li.
