Abstract
We review the experimental evidence for alpha chain states in 4N-nuclei. Bloch-Brink cranked cluster model calculations suggest that such states should exist in all light A = 4N nuclei. Recently a strong resonance has been observed in the 12C(12C,12C(0 +2 ))12C(0 +2 ) reaction at 33 MeV which has been taken as evidence of a 6-α chain state in 24Mg. The angular distributions show strong peaks at 90° due to the simultaneous excitation of several nearly degenerate resonances with a range of L-values. We review our analysis of these data and present the results of calculations for the widths of resonances in hyperdeformed nuclei. We demonstrate that such resonances may have relatively narrow widths despite their high excitation energies. We surmise that the 33 MeV resonance in 12C + 12C scattering has a chain state structure.
