In a track nuclear photoemulsion exposed to a beam of {sup 7}Li nuclei accelerated to a momentum of 3 GeV/c per nucleon at the synchrophasotron of the Joint Institute for Nuclear Research (JINR, Dubna), 13 events in which {sup 7}Li nuclei interacting with protons break up into {sup 3}H and {sup 4}He fragments were detected among 3730 inelastic-interaction events. For this fragmentation channel, the cross section was found to be 8 {+-} 2 mb. The average value of the fragment total transverse momentum was 214 {+-} 5 MeV/c. This value exceeds markedly the average value of the transverse-momentum transfer in the coherent dissociation of {sup 7}Li nuclei on track-emulsion nuclei (166{+-}5MeV/c). The recoil-proton transverse momentum was on average 98% of the total proton momentum. The longitudinal-momentum distribution of protons was characterized by a variance of 16 MeV/c and a mean value of 37 {+-} 2MeV/c.
