Abstract:

Studies were conducted to establish the technical feasibili y of obtaining neutron diffraction d ta on specime s 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 transform d completely t 60,000 psi, but only an incomplete transition was observed in bCl. There are indications of possible differences in the transformation mechanism for these m terials. I is concluded that neutron Laue patterns are feasibl at pressures up to 80,000 psi a th he method coul be extended to per aps 150,000 psi. Author
