Calculations have been performed to explore the effect of configuration mixing in a large basis on the fragmentation of stretched'' {ital M}6 strength in the {ital sd}-shell nuclei {sup 20}Ne, {sup 24}Mg, {sup 28}Si, {sup 32}S, and {sup 36}Ar. This work elaborates on results for {sup 28}Si given previously, extends those calculations to neighboring {ital N}={ital Z} nuclei with the same basis restriction (one particle in the 1{ital f}{sub 7/2} orbit and up to four particles in the 1{ital d}{sub 3/2} orbit) used in that earlier paper, and examines all self-conjugate {ital sd}-shell nuclei in a basis with one particle in the 1{ital f}{sub 7/2} orbit and unrestricted occupancy of the {ital sd}-shell orbits. It is found that configuration mixing in a large basis reproduces interesting features of the spectrum for {sup 28}Si and {sup 32}S and gives an improved description of other properties of the observed 6{sup {minus}} states, but fails to describe the observed spectrum in {sup 24}Mg. Emphasis is placed on the location of additional observable fragments of the {ital M}6 response.
