The alpha-d cluster structure of Li-6 has been extensively investigated in the past few decades. In particular the width of the alpha momentum distribution in Li-6 has been studied as a function of the transferred momentum. These investigations are now reviewed and updated after recent experiments. Trojan horse method applications are also discussed because the momentum distribution of the spectator particle inside the Trojan horse nucleus is a necessary input for this method. The impact of the width (FWHM) variation in the extraction of the astrophysical S(E) factor is discussed for the Li-6(d,alpha)He-4 reaction.
