The total average spin of the fragments is measured for B10,11 as projectiles and Np237 as target at energies around coulomb barrier for fragments emitted in 165°, 150°, 105° and 90° relative to beam direction using γ−raymultiplicity 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.
