For JENDL-3.1, total and capture cross sections were
calculated with optical and statistical model.
The spherical optical potential parameters were evaluated
to reproduce experimental total cross sections /11,12,13/.
V = 50.71-0.4793*En MeV r0= 1.227 fm a0= 0.663 fm

Vso= 6.560 MeV rso=0.046 fm aso=0.535 fm
Optical and statistical model calculation was performed
with casthy code /14/.
For JENDL fusion file, cross sections for (n,2n), (n,np),
(n,na) and inelastic scattering were calculated with
sincros-ii code system/2/ by adopting Walter-Guss omp
modified by Yamamuro/2/ for neutrons, Lemos omp modified
by Arthur and Young/15/ for alpha, Lohr-Haeberli/16/ for
deuteron, Becchetti-Greenlees/17/ for triton and he-3.
level density parameters used are:
V-52 9.0 (1/MeV)
V-51 8.6
V-50 8.6
Ti-51 9.8
Ti-50 8.6

Gilbert-Cameron level density formula, as modified by
Yamamuro to take account of the shell-correction factor,
was employed.
