Variation of the matter densities of nuclei from /sup 40/Ca to /sup 68/Zn
Analysis is made of elastic scattering of 42 MeV ..cap alpha..-particles from 19 nuclei from /sup 40/Ca to /sup 68/Zn in terms of a folding model, allowing determination of matter densities in the nuclear surface region relative to that of /sup 40/Ca. Specifically, values are deduced for the radii at which the matter density equals 0.016 nucleon/fm/sup 3/ as well as matter rms radii. The relative sizes vary more slowly than A/sup 1/3/ betwen /sup 40/Ca and /sup 54/Fe and more rapidly than A/sup 1/3/ between /sup 54/Fe and /sup 68/Zn. The overall trend gives an increase with A/sup 1/3/ but with a bowing effect. The near equality of proton and matter rms radii indicates that the neutron-proton radii are approximately equal to within the errors of the present analysis. The results are in reasonable agreement with those obtained with other hadronic probes and with calculated Hartree-Fock-Bogoliubov densities.
