Abstract: Studies were conducted to establish the technical
feasibility of obtaining neutron diffraction data on
specimens under high hydrostatic pressure. Laue
patterns of RbI and RbCl were obtained at pressures
up to 80,000 psi in a uniquely designed pressure
bomb. The RbI transformed completely at 60,000 psi,
but only an incomplete transition was observed in RbCl.
There are indications of possible differences in the
transformation mechanism for these materials. It is
concluded that neutron Laue patterns are feasible at
pressures up to 80,000 psi and that the method could
be extended to perhaps 150,000 psi.
