Comments about isobar separation at HRIBF:
 Mass excess values are from the 2003 mass table of
G. Audi, A. H. Wapstra and C. Thibault,
Nuclear Physics A729 (2003) p. 337676.
This version of the
Mass Table
was taken from NNDC at BNL;
 Isobaric mass differences are given as
M/ΔM = A1 * 931.494013 / (M1  M2)
where M1 is the mass of the desired beam and M2 is the
mass of the neighboring isobars.
 The isobar separator has a resolving power of M/ΔM~20,000; however,
the isobaric separation actually achieved will depend not only on
isobaric mass differences but also on the beam emittance, energy spread,
and isobar intensity ratios.
 The dispersion of the isobaric separator is given by:
dx(mm) = 5163 * ΔM/M (or ΔE/E if energy spread dominates).
This corresponds to 0.258 mm for M/ΔM = 20,000.
 Partial isobaric separation will usually be possible for
M/ΔM<10,000, but may result in reduced beam intensity.
