In order to search for a proposed alpha : 2n : alpha : 2n : alpha molecular
structure in C-16 its break-up into Be-10 + He-6, Be-12 + alpha, He-8 + 2
alpha and He-6 + He-6 + alpha has been studied using a 560 MeV C-16 beam in
elastically excited on a C-12 target. States in C-16 appear to be only weak
ly populated in this reaction.
