CLAS
dates back to the bubble chamber era as early as 1959. Using the high lumi-
nosity photon beam incident on a long (40 cm) liquid hydrogen target at Hall
B of Jefferson Lab, data was mined from the g12 experiment using the CLAS
detector. The detector was used to identify a final state with a proton in coinci-
dence with a scattered Lambda baryon. The initial Lambda, before scattering,
was produced via the γp → K +Λ reaction, for which the cross section is well
known. Using the known flux of Λ particles, preliminary measurements of the
Λ − p cross section will be presented. Future directions of related possibilities
for measuring hyperon-nucleon scattering at CLAS will be discussed.
