We analyze the elastic scattering of protons on a 4n system. This was used as part of the detection technique of a recent experiment [<article>F. M. Marqués et al. Phys. Rev. C 65, 044006 (2002)</article>] to search for the 4n (tetraneutron) as a bound particle. We show that it is unlikely that this process alone could yield the events reported in <article>F. M. Marqués et al., [Phys. Rev. C 65, 044006 (2002)]</article>, unless the 4n has an anomalously large backward elastic scattering amplitude.
