Abstract：
In this paper, an exact boson representation of the antisymmetrizer has been derived. The effect of the antisymmetrization is expressed by different kinds of many-body forces in boson space. An estimation to the importance of many-boson forces has made. With the inclusion of the three-boson force, a calculation of the spectrum of a six fermions system in j=13/2 shell has been carried out in boson space and exact coincidence with the exact spectrum is recovered. We found that the 3-boson force is indispensable when the fermion space is crowded.
