The total average spin of the fragments is measured for $B^{10,11}$ as projectiles and $Np^{237}$ as target at energies around coulomb barrier for fragments emitted in $165^{\circ}$, $150^{\circ}$, $105^{\circ}$ and $90^{\circ}$ relative to beam direction using $\gamma-ray$multiplicity measurement method. Theoretical calculations have been performed by using Transition State Model(TSM). Measured fragments spin show a weak angle dependence when compared to the calculated results using TSM. In the framework of TSM the angular distribution of $K$ degree of freedom. To explain the weak measured emission angle dependence of fragments spin, the gaussian distribution that was considered for $K$ should be considerably modified.
