Experiment E12-17-003 searches for the nnΛ state through the 3H(e,e'K+)nnΛ reaction at JLab Hall A.
The experiment used two HRSs to measure e' and K+ at
the central momenta of 2.2 and 1.8 GeV/c, respectively,
and scattering angles of
θee' = θeK = 13.2 degrees.
The experiment was carried out from Oct 29 to Nov 25 in 2018.
