Abstract
The sizes of emission sources of deuterons and a particles were determined in minimum bias O-16-p collisions at 3.25A GeV/c from the analysis of experimental one-dimensional correlation functions of these particles, based on a theoretical model assuming the simultaneous excitation and decay of sources (of identical particles), whose coordinates are distributed according to a Gaussian function. The peak was observed in the experimental correlation function of the pairs of a particles in the region of q < 25 MeV/c, which was deduced to be due to decays of unstable Be-8 and B-9 nuclei at various kinetic energies. This result does not contradict the popular assumption of other authors about the existence of the alpha-condensate state in the O-16 nucleus since unstable Be-8 and B-9 nuclei themselves can probably be formed from decay of the alpha-condensate state of the oxygen nucleus if such a state does exist.
