Cross sections as well as vector and tensor analyzing powers for the 2H(d,n) 3He reactions at energies around 30 keV are analyzed by the invariant-amplitude method. In addition, microscopic four-body calculations along the Faddeev-Yakubovsky method are reported, with limitations only on the interactions and intermediate states of the three-nucleon subsystem. The suppression of the cross section due to simultaneous polarizations of the projectile and the target is discussed comparing the results from both of these methods as well as from earlier works.
