Environmental concerns demand that all tritium releases be minimized. In particular an experiment recently fielded at Los Alamos National Laboratory required a 4 mm3 volume to be dynamically filled to a pressure of 7 MPa, while keeping the total trit

The intermetallic compound Zr 2 Cu with the tetragonal MoSi 2 -type structure produces a metastable ternary hydride Zr 2 CuH x . Powder X-ray diffraction indicated a monoclinic unit cell for this phase when x = 4.2. Nuclear magnetic resonance of the

Experimental results from a NMR study of {sup 3}He in nanometer-sized microbubbles in aged palladium tritide over the temperature range 4--300 K are presented. A determination of the rigid-lattice--line-shape second moment at 4 K provides a value for

Nuclear magnetic resonance (NMR) measurements of the proton spin-lattice and rotating-frame relaxation times were made on Ti 2 PdH x over the temperature range 100–580 K. Analyses of the NMR data for Ti 2 PdH x gave hydrogen diffusion parameters th

Experimental studies of helium release from aged PdT{sub {ital x}} show that the helium-to-metal-atom ratio saturates at a value of (He)/(Pd){congruent}0.5 under conditions of ambient-temperature storage. Below this value, very little helium release

A semi-empirical method for detemining structural stability in molecules and in certain solids is presented. The method is related to the resonance energy concept of HMO theory. A general topological stability index is defined and shown to be well co

This article gives a microscopic description of magnetism in the Fe group, based on tetratomic spin-polarized Jahn-Teller resonance states. Ferromagnetism is due to Hund's-rule intra-atomic exchange coupling between molecular magnetic states having a

Pulsed NMR relaxation-time measurements have been performed on PdT/sub x/, aged approximately eight years, after first removing most of the tritium by room-temperature desorption and again after addition of protium to one of these tritide-free sample

Nuclear magnetic resonance relaxation times for /sup 3/He in microscopic bubbles in 1-yr-old Pd/sup 3/H/sub 0.62/ have been measured in the range 100--320 K. The results provide evidence for the melting of He in the range 200--280 K and for He diffus
