We study the effect of virtual Coulomb breakup, commonly known as the dipole polarizability, of the deuteron projectile on the astrophysical fusion reaction 3He(d,p)4He. We use the adiabatic approximation to estimate the potential shift due to the E1 transition to the continuum states in the deuteron and compute the barrier penetrability in the WKB approximation. We find that the enhancement of the penetrability due to the deuteron breakup is too small to resolve the longstanding puzzle observed in laboratory measurements that the electron screening effect is surprisingly larger than theoretical prediction based on an atomic physics model. The effect of 3He breakup in the 3He(d,p)4He reaction, as well as the 7Li breakup in the 7Li(p,\ensuremathα)4He reaction is also discussed.
