Description

As part of the first phase program of experiments utilizing the
SAMURAI spectrometer and NEBULA neutron array, we have undertaken
invariant mass spectroscopy of 18,19,20,21B using the complementary
probes of neutron and proton knockout. After a brief introduction to
the experimental setup and analysis techniques, the results for 18,19B
are discussed where, in addition to substantially improving our
knowledge of the known threshold states in both systems, evidence for
new levels has been found. Finally, the first observations of 20,21B
are presented.
