A study of 24Mg by 16O + α + α cluster model

The semi-microscopic calculation of 16O + α + α cluster model is performed with the orthogonality condition model. Energy spectra of 24Mg are obtained, and the structures of the levels are discussed through the wave functions. Low-lying levels are classified into four rotational bands which correspond to the observed K sup(π) = 01+, 2+, 02+ and 0- bands. The calculated fourth and fifth 0+ states show a characteristic feature in the reduced width amplitudes which indicates a large clusterization into 20Ne plus α. Electric transition probabilities and α + 20Ne and 8Be + 16O spectroscopic factors are calculated and discussed. (author)
