Data on the yields of hydrogen isotopes (p, d, t) and helium isotopes (from

He to
8
He) at the angle of 3.5° in fragmentation of the carbon ions with the energy of 0.3 GeV/nucleon on the beryllium ...target are reported. The momentum spectra of the fragments in the rest frame of the fragmenting nucleus are measured in a considerably larger momentum range than in the previous experiments.

= 0.3, 0.6, 0.95, and 2.0 GeV/nucleon on a Be target were measured in the FRAGM experiment at TWA-ITEP heavy-ion facility. ...Proton momentum spectra cover both the region of the fragmentation maximum and the cumulative region. The differential cross sections span six orders of its magnitude. The spectra are compared with the predictions of four models of ion-ion interactions: LAQGSM03.03, SHIELD-HIT, QMD, and BC.
The abrasive finishing of a zirconium–ceramic composite is studied experimentally. The influence of the type of abrasive and its grain size on the productivity and on the final surface roughness of ...the zirconium ceramic is considered.
Grinding of the ends of lithium-niobate monocrystalline plates by bound abrasive is considered. The diamond laps employed are based on ASN micropowder (grain size 10/7), with organic and metallic ...binders. In grinding by laps with organic binder, the rate at which material is removed is 16–20% higher than for laps with metallic binder. The roughness of the ground end surfaces of the lithium-niobate monocrystalline plates is practically independent of the applied pressure and the cutting speed.
