None Unable to produce 27Al(n,g)28Al Reaction

I am working on a cavity style detector consisting of a sensitive volume of gas surrounded by a wall of Aluminum and containing a thin wafer of boron carbide. One important reaction I need to see is the 27Al(n,g)28Al reaction which should have a cross section of ~12 barns for thermal neutrons however I am not seeing it. I am using the physics list "QGSP_BIC_HP" with no alterations or cuts set for the volumes in DetectorConstruction. I see other neutron capture reactions such as 10B+n->a+7Li+g so I am baffled as to why I don't see the Al reaction.

If anybody can share any insight into why I don't see the 27Al capture reaction it would be greatly appreciated and if more information is needed I can provide it.
