Data are reported at energies of 160 to 420 Mev for the scatteriug of electrons by Be/sup 9/, B/sup 10/, B/sup 11/, N/sup 14/ and O/ sup 16/. A detailed analysis of these elastic scattering data and other available data for p- shell nuclei is carried through, using various methods and a wide variety of assumed functional forms of the nuclear charge distribution. It is possible to fix rather accurately the spherically symmetric part of the charge distributions of Li/sup 6/ C/sup 12/, N/sup 14/, and O/sup 16/, and with less accuracy, those of Be/sup 9/ and B/sup 11/. Central densities are uncertain in all cases. Quadrupole scattering appears to be important in N/sup 14/, in B/sup 11/, and possibly in Be/sup 9/, and a crude estimate of the quadrupole moment of N/sup 14/ is inferred from the data. The quadrupole scattering depends sensitively on the source of the quadrupole moment, as well as on its value. Regularities within the p-shell are discussed, and connection made with the properties of heavier nuclei. Be/sup 9/ and all heavier nuclei have a common value of peak particle density corresponding to a mean particle spacing of (1.13 plus or minus 0.01) x 10/sup -13/ cm. Only Li/sup 6/ fails to reach this density of saturated nuclear matter. (auth)
