3] are the number of unit cells along the three crystal axes a, b, and c when the crystallite is assumed to be a parallelepiped.
58 nm, respectively, and thus the intersections between the phonon curves [9] and the dispersion curve for a neutron indicating the most effective incident neutron energy for UCN production with a single phonon creation process, are strongly dependent on the relative angle between the crystal axes and the direction of the neutron incidence.
In each region, the stripes run along one of the two perpendicular crystal axes.
The motifs are parallel throughout the entire polycrystalline aggregate, and the crystal axes change across grain boundaries.
In this case, an electron pair would instead have a wave function with d-wave symmetry, resembling a four-leaf clover that has its lobes aligned along the crystal axes.
In the d-wave case, the wave function of the electron pair resembles a four-leaf clover, with lobes aligned along the crystal axes of the material (see illustration below).
The researchers also found that the ratio of distancesbetween molecules lying along two different crystal axes decreased with increasing pressure.
These grains have been fractured along their crystal axes in the same way that quartz grains found near craters and nuclear explosion sites have been fractured when the shock waves from such events ripped through the crust.
