  In the absence of accurate data on the free two-body hyperon-nucleon
interaction, the spectra of hypernuclei can provide information on the details
of the effective hyperon-nucleon interaction. Electroproduction of the
hypernucleus Lambda-9Li has been studied for the first time with sub-MeV energy
resolution in Hall A at Jefferson Lab on a 9Be target. In order to increase the
counting rate and to provide unambiguous kaon identification, two
superconducting septum magnets and a Ring Imaging CHerenkov detector (RICH)
were added to the Hall A standard equipment. The cross section to low-lying
states of Lambda-9Li is concentrated within 3 MeV of the ground state and can
be fitted with four peaks. The positions of the doublets agree with theory
while a disagreement could exist with respect to the relative strengths of the
peaks in the doublets. A Lambda separation energy of 8.36 +- 0.08 (stat.) +-
0.08 (syst.) MeV was measured, in agreement with an earlier experiment.
