We propose a new approach that implements the underlying symmetries of each isotope with a few parameters directly in the density. Various densities and their nuclear structure are then analyzed in the reactions of $^{12}$C and $^{11}$Li, $^{11}$Be, and $^{11}$C on a carbon target.RevTeX, 21 pages, 6 Tables, 6 Figures in a separate .ps fileNuclear Theorytext
