Tagging in T(b) (I) 1M events of e + Pb208 collisions at 10  40 GeV/n with 1 < Q2 < 20, 0.3 < y < 0.95, parameter settings tuned by Mark, genShd = 3 x < 0.002 cut leaves ~38% of events Comparison of tagging statistics for evaporation neutrons all neutrons all combinations of neutron, proton, deuteron, and  multiplicities true T(b) data all combinations of atomic number A and evaporation neutron multiplicity

Tagging in T(b) (II) Same data sample as on page 1 Comparison of tagging statistics for evaporation neutrons residual nucleus rigidity A of residual nucleus true T(b) data all combinations of atomic number A and evaporation neutron multiplicity

To Do T(b) plots A combined with evaporation neutron multiplicity  ratio of T(b) to that of evaporation neutrons to the 10/3 power  d plots  same as for T(b) but with x > 0.02 cut using second data sample (in progress) T(b) plots using simulation data for particles detected after the downstream ion quad triplet (in progress) evaporation neutron multiplicity total neutron multiplicity evaporation proton multiplicity total proton multiplicity A of residual nucleus rigidity of residual nucleus d plots using simulation data for particles detected after the downstream ion quad triplet same as for T(b) but with x > 0.02 cut using the second data sample
