Abstract：
The spin transverse response functions for ⁴⁰Ca and ¹²C in different approximations have been calculated.By using the coupled RPA equations for polarization propagator including the delta degree of freedom,the influence of the delta on the response function has been investigated.The results show that they are reduced explicitly.Introducing the energy dependent effective nucleon mass,which embodies the manybody ef ects,the satisfactory results are obtained.
