If iidfs=1 is specified, the multiplicity  :math:`\nu`  and energy spectra  of neutrons from neutron-induced fission taken from reference  [#]_  are used instead of the nuclear library data for the following 18  nuclei: U-238, Pu-238, Pu-240, Pu-242, Cm-242, Cm-244, Cf-252, Th-232, U-232,  U-233, U-234, U-235, U-236, Np-237, Pu-239, Pu-241, Am-241, and Bk-249. 

With the idwba=1 setting, the discrete spectra calculated by the  DWBA are added to the neutron and proton  spectra obtained using other nuclear reaction models for the following  reactions:

 | :math:`^7` Li :math:`(p,n)^7` Be reactions at 30--400 MeV
 | :math:`^9` Be :math:`(p,n)^9` B reactions at 10--50 MeV
 | :math:`^{6,7}` Li :math:`(d,n)^{7,8}` Be and  :math:`^{6,7}` Li :math:`(d,p)^{7,8}` Li reactions at  10--50 MeV
 | :math:`^9` Be :math:`(d,n)^{10}` B and  :math:`^9` Be :math:`(d,p)^{10}` Be reactions at 5--25 MeV
 | :math:`^{12,13}` C :math:`(d,n)^{13,14}`  and  :math:`^{12,13}` C :math:`(d,p)^{13,14}` C reactions at  10--50 MeV

See the reference   [#]_  for more details.

If a particle with a decay channel (See  :numref:`tbl-decay` ) has an energy lower than the cut-off,  the particle decays completely.  Negative-charged pions ( :math:`\pi^-` ) with the setting of npidk=0 are  forced to be absorbed by nucleus.  If  :math:`\pi^-`  is not able to be absorbed in the program, the particle decays (to prevent an infinite calculation loop).
