Query: Nuclear breakup of $^8$B in a direct fragmentation model   We calculate the cross sections of the elastic and inelastic breakup modes
for the inclusive breakup reaction $^{28}$Si($^8$B,$^7$Be) at beam energies
between 10 - 40 MeV/nucleon within a direct fragmentation model formulated in
the framework of the post form distorted-wave Born-approximation. In contrast
to the case of the stable isotopes, the inelastic breakup mode is found to
contribute only upto 30% to the total breakup cross section, which is in
agreement with the recently measured experimental data. However, the high
energy tail of the energy spectra of $^7$Be fragment is dominated by the
inelastic breakup mode. The breakup amplitude is found to be dominated by the
contributions from distrances well beyond the nuclear surface.
