ALPHA-CLUSTER STRUCTURE OF THE AR-36 NUCLEUS

Angular correlation functions are measured for the d alpha system in t he reaction S-32(Li-6, d)Ar-36(alpha)S-32 induced by 22- and 38-MeV L i-6 ions. It is found that, in the Ar-36 nucleus, there exist 5(-), 6( +), 7(-), 8(+), and 10(+) alpha-cluster states occurring in the excita tion-energy range 11-25 MeV and forming a rotational band without pari ty splitting. These results supplement the pattern of the alpha-cluste r structure of excited states that is currently believed to exist in l ight even-even nuclei from O-16 to Ti-44.
