We present angular correlations in {open_quote}{open_quote}Basel{close_quote}{close_quote} coordinates for {alpha}-particle decay in measurements of {sup 12}C[{sup 12}C,{sup 12}C(3{sub 1}{sup {minus}}){r_arrow}{sup 8}Be(0{sub 1}{sup +})+ {alpha}]{sup 12}C{sup {asterisk}} scattering at {ital E}{sub c.m.}=32.5 MeV. A semiclassical model of the angular correlation function has been used to describe the observed angular correlations in the various exit channels. We demonstrate that the semiclassical result can be used even in the case where there are two nonzero spins in the exit channel if the decay products from both ejectiles are detected. We apply this new method to the mutual sequential breakup reaction {sup 12}C[{sup 12}C,{sup 12}C(3{sub 1}{sup {minus}}){r_arrow}{sup 8}Be(0{sub 1}{sup +})+{alpha}]{sup 12}C(3{sub 1}{sup {minus}}) {r_arrow}{sup 8}Be(0{sub 1}{sup +})+{alpha}. We deduce that the scattering occurs dominantly to a final state with fully aligned spins and orbital angular momentum {ital L}{sup {prime}}=12 or 14. {copyright} {ital 1996 The American Physical Society.}
