【 摘 要 】

Cluster structure of highly excited states of24Mg has been investigated by the antisymmetrized molecular dynamics. Imposing the constraints on the expectation values of harmonic oscillator quanta, α+20Ne,12C+12C and 6α cluster wave functions were generated without any a priori assumption. The isoscalar monopole excitation function is also calculated and reasonably agrees with the observation. It is found that α+20Ne,12C+12C and 6α clusters appear as the prominent peaks in the strength function.
