  The inclusive energy distributions of fragments (4$\leq$Z$\leq$7) emitted in
the reactions $^{16}$O (116 MeV) + $^{27}$Al, $^{28}$Si, $^{20}$Ne (145 MeV) +
$^{27}$Al, $^{59}$Co have been measured in the angular range $\theta_{lab} $=
10$^\circ$ - 65$^\circ$. Fusion-fission and deep inelastic components of the
fragment emission have been extracted from the experimental data. The angular
mometum dissipations in fully damped deep inelastic collisions have been
estimated assming exit channel configuration similar to those for
fusion-fission process. It has been found that, the angular momentum
dissipations are more than those predicted by the empirical sticking limit in
all cases. The deviation is found to increase with increasing charge transfer
(lighter fragments). Qualitatively, this may be due to stronger friction in the
exit channel. Moreover, for the heavier system $^{20}$Ne + $^{59}$Co, the
overall magnitude of deviation is less as compared to those for the lighter
systems, {\it i.e.}, $^{16}$O + $^{27}$Al, $^{28}$Si, $^{20}$Ne + $^{27}$Al.
This may be due to lesser overlap in time scales of fusion and deep inelastic
time scales for heavier systems.
