WebNov 13, 2024 · Even if all the nuclear density distributions cannot be determined, the nuclear surface “diffuseness”, which quantifies the nuclear surface thickness, is a promising measure of the surface density profile and can be deduced accurately using nucleus–proton scattering as demonstrated in Ref. [ 15 ]. WebAs a rule of thumb, the Nuclear Method density tests can be used as a quick CQC check or indicator of the rockfill compactive effort, however these CQC rockfill density tests should be confirmed with large scale density test methods described in this article for a more representative and accurate determination of the in-place rockfill dry density.
