 note = {We have measured the double-differential cross sections for
neutron production from C, Ne and Ar projectiles at
$E/A$ = 290 - 600 MeV on C, Cu and Pb targets.
Neutron energies were measured at laboratory angles
between 5 and 80 degrees.
The measured neutron spectra have three components.
At forward angles, a prominent peak originating from the
projectile-fragmentation process was observed.
The velocity of neutrons corresponding to the peak was about the same as
that of the projectile.
In addition to the peak, two components of Maxwellian-shape distributions
corresponding to the pre-equilibrium and equilibrium processes were observed.
By fitting with a moving-source model having three components, the neutron
spectra were fairly well described.
The parameters obtained for each component are consistent with a picture
of the projectile fragmentation, pre-equilibrium and equilibrium processes.
By integrating the fitted functions with respect to the neutron energies
and solid angles, the angular distributions and total cross sections
for the neutron production were determined.
The neutron spectra, angular distributions and total cross sections were
compared with those calculated by the QMD and HIC codes.
We found that neither of the codes could reproduce the measured
cross sections for all combinations of the projectiles and targets.},
