We have repeated the experiment of Taleyarkhan et al. in an attempt to detect the emission of neutrons from d-d fusion during bubble collapse in deuterated acetone. Using the same apparatus, a more sophisticated data acquisition system, and a larger scintillator detector, we find no evidence for 2.5-MeV neutron emission correlated with sonoluminescence from the collapsing bubbles. Any neutron e...

We investigate the possibility that the process of ρ 0-meson photoproduc-tion on proton, γ + p → p + ρ 0 , in the near threshold region E γ < 2 GeV, can be considered in the framework of model with π-, σ-and N-exchanges. This suggestion is based on a study of the t-dependence of differential cross section, dσ(γp → pρ 0)/dt, which has been measured by SAPHIR Collaboration. We find that the sugge...

The double differential emission spectra for fusion-produced alpha-particle and neutron as a function of emission energy and angle relative to the direction of beam injection are examined on the basis of the one dimensional (1D) Boltzmann-Fokker-Planck (BFP) model in beam-injected (non-Maxwellian) deuterium-tritium (DT) plasmas. It is shown that owing to the existence of energetic component in ...
