h.c.p.-f.c.c. phase transition in solid parahydrogen

The difference of free energies for the h.c.p. and f.c.c. parahydrogen is calculated as a function of molar volume. It is shown that the observed transition in solid parahydrogen¹ can be explained by differences in the structure of the cubic and quartic anharmonic terms.     

Sputtering yield measurements on H. C. P. and F. C. C. cobalt V. S. chernysh

A computer code previously set up to simulate ion penetration in amorphous solids has been extended to handle with recoil phenomena. Preliminary results are compared with existing experimental data.     

Diffraction dissociation into high masses at N.A.L.-I.S.R. energies

The triple-pomeron picture of diffraction dissociation into high masses, combined with recent observations about the dominance of short-range correlations in multiparticle production at very high energies, implies that the cross section for diffractive dissociation into high masses rises approximately logarithmically in the NAL-ISR energy range. Predictions are also made about the multiplicity distribution of diffractively-produced particles.
