  We have measured the production rates and production cross sections for a
variety of radioactive isotopes which were produced from 124Xe, 48Ca, and 238U
beams at an energy of 345 MeV/nucleon using the BigRIPS separator at the RIKEN
Nishina Center RI Beam Factory (RIBF). Proton-rich isotopes with atomic numbers
Z = 40 to 52 and neutron-rich isotopes with Z = 5 to 16 were produced by
projectile fragmentation of the 124Xe and 48Ca beam on Be targets,
respectively. Neutron-rich isotopes with Z = 20 to 59 were produced by
in-flight fission of the 238U beam, in which both Be and Pb were used as
production targets. The measured production rates and production cross sections
were compared with those of the LISE++ calculations, and overall fairly good
agreement has been obtained. Furthermore, in the measurements with the 124Xe
beam, we have discovered four new isotopes on the proton-drip line, 85,86Ru and
81,82Mo, and obtained the clear evidence that 103Sb is particle unbound with an
upper limit of 49 ns for the half-life. The measurements of projectile-fragment
momentum distributions have been also performed with the 124Xe beam, in which
the low-momentum tails of the distributions have been measured for the first
time at the energy of 345 MeV/nucleon.
