Re: Dangers of Pu / Air Activation c.s.

About the Tony Hillerman reference:

  Tony Hillerman is an author who writes mystery novels situated 
in & around the Navajo reservation along the New Mexico/Arizona
border...  though I haven't read _People of Darkness_, the 
Hillerman books I have read are quite good.  Especially if
you're new to the area.  

ok, now for an HP-related question:  are there any references
that discuss cross sections of high-energy proton reactions?
I'm doing some research at the Los Alamos Meson Physics Facility
involving controlling activated air emissions.  I want to predict
the generation of carbon-11 thru direct production (proton
interactions) as well as indirect (neutron interactions). 

  ( A little background:  LAMPF is an 800 MeV proton accelerator,
operating at 1 milliampere of current.)

  The only values I can find are for energies "greater than 100 MeV"  
and the like...   I believe the main reactions of interest are 
the following:   N14(p,alpha)C11   and   O16(p,alpha+p+n)C11
Neutron reactions are  N14(n,p+3n)C11  and  O16(n,alpha+2n)C11

Feel free to respond by direct e-mail, or via RADSAFE.  Thanks
for the help!
