Abstract
We study the energy dependence of the cross sections for nucleon removal of ${}^{8}\mathrm{B}$ projectiles. It is shown that the Glauber model calculations with nucleon-nucleon $t$-matrix reproduce well the energy dependence of the breakup cross sections of ${}^{8}\mathrm{B}.$ A distorted wave Born approximation (DWBA) model for the breakup cross section is also proposed and results are compared with those of the Glauber model. We show that to obtain an agreement between the DWBA calculations, the Glauber formalism, and the experimental data, it is necessary to modify the energy behavior of the effective interaction. In particular, the breakup potential has a quite different energy dependence than the strong absorption potential.
