Question How to multiply the flux by a specific cross section ?

Hello

I want to simulate the response of a He3 detector, embeded in a polyethylene
moderator, to a flux of neutrons. Because of the low density of He3, the
 actual He3(n,p) events will be very rare in a simulation (I guess). Therefore
I want to:

   1. calculate the neutron flux in the detector volume as a function of
energy (over some 9-10 decades). I found that this can be done, quite
tediously, with a regular flux scorer + ParticleFilterWithKineticEnergy (or
something like that) for every energy bin requested. I want 200 , 20 per
decade.

   2. multiply the calculated flux, at the end of the run, by the He3(n,p)
cross section, as a function of energy.

THe question is: How can I get the He3(n,p) cross section values, at the end of the run ?
