      abstract     = {The effect of the addition of n-hexanol as co-surfactant on
                      the structure of cetyltrimethylammonium bromide (CTAB)
                      micelles has been studied using small-angle X-ray and
                      neutron scattering (SAXS, SANS). Contrast variation neutron
                      scattering experiments were performed to determine the
                      structure of both pure CTAB and n-hexanol modified CTAB
                      micelles. The incorporation of n-hexanol leads to an
                      elongation of the ellipsoidal CTAB micelles. The scattering
                      length density of the micellar shell linearly depends on the
                      degree of deuteration of the dispersion medium water and
                      revealed the existence of substantial amounts of water in
                      the micellar shell. The water content in the shell increased
                      from $20 vol-\%$ observed for pure CTAB micelles to
                      $44 vol-\%$ found for n-hexanol modified CTAB micelles.
                      The amount of n-hexanol in the micellar shell was determined
                      by varying the amount of fully deuterated and protonated
                      n-hexanol. These experiments revealed a volume fraction of
                      $26 vol-\%$ of n-hexanol molecules in the micellar core
                      which equals a molar fraction of $50 \%$ n-hexanol within
                      the CTAB micelles. The total composition of micellar core
                      and shell was estimated. The packing density of headgroups,
                      water molecules and bromide ions turned out to drastically
                      increase in n-hexanol modified CTAB micelles. These findings
                      contribute to a fundamental understanding of the
                      stabilization mechanism of micelles by alcoholic
                      co-surfactants and the resulting alteration of the
                      morphology and interface composition. These results will
                      facilitate the optimization of processes where CTAB and
                      other comparable surfactants are used as phase transfer
                      catalysts, structure directing agents or stabilizers in
                      colloidal dispersions or emulsions.},
