Impulse distribution of theα−dmotion inLi6

We have reanalyzed previous data on the ${}_{}{}^6{}_{}{}^{}\mathrm{Li}$($p$,$\mathrm{pd}$) quasifree scattering at 590 MeV incident energy, from which the authors deduce a momentum distribution of the clusters $\alpha$ and $d$ in ${}_{}{}^6{}_{}{}^{}\mathrm{Li}$ with a full width at half maximum around 120 MeV/c. We find instead that the experimental results are compatible with a momentum distribution whose full width at half maximum is about 70 MeV/c, which is in agreement with other experimental findings and with the prediction of the cluster model.
