I'm in need of stable isotopic Cu (Cu-63 & Cu-65) for use in a thin film
evaporator.  We're preparing a multilayer strucuture in which we will use
small angle neutron diffraction as a sensitive technique for studying
interdiffusion.  Ideally I need about 2 g of each with isotopic purities of
>90%.  Oak Ridge is the only source I'm aware of in the States.  Does
anyone have a connection with the Former Soviet Union.  I'm hoping such
things are available (at less than $4/mg price ORNL charges) from our new
allies.  Any leads?
