Figure 4.16.: Same as in figure 4.15, but now for the data combined for all neutron
multiplicities. The lines present the conditions which are applied in the
further analysis to distinguish the different multiplicities.

Table 4.5.: Neutron separation matrices for multiplicities of 1 to 5 neutrons. Columns
display the neutron multiplicity simulated, rows the neutron multiplicity derived
from the neutron tracking algorithm. Values are given in percent. Neutrons
were simulated with 200 (left), 600 (middle) and 1000 MeV (right matrix).
NeuLAND was located at a distance of 15.5 m to the target. Neutrons
were generated with a relative energy of 500 keV with respect to a medium
heavy projectile fragment. The distance between target and NeuLAND was
filled with air.
