Abstract :
Low energy capture and transfer reactions of the astrophysical 
interest in the four-nucleons system are studied in the microscopic cluster
model in order to manifest the role of the tensor force in these reactions.
In this model, each cluster wave functions are given by the precious
few-body wave functions which is selected by the stochastic
variational method with the AV8' realistic interaction
and the phenomenological three-body force. Cross sections are
calculated by the microscopic R-matrix method and the results are compared 
with those with the Minnesota (MN) effective potential. Our results show 
that the tensor force plays an indespensable role in order to reproduce 
the zero energy astrophysical S-facor not only in the capture reaction, 
2H(d,gamma)4He, but also in the transfer reaction, 2H(d,p)3H and 
2H(d,n)3He.
