| Research Abstract |
In order to verify a hypothesis that atmospheric ions produced by ionization of cosmic-rays promote formation and growth of aerosol particles and control the earth's climate, we conducted a preliminary study on laboratory experiments. A system has been constructed for introduction of syntesis air with minor constituents to a reaction chamber and measurement of reaction products after irradiation of UV lights and ionizing radiation. We irradiated beta-rays or heavy ion beam and measured ion density, aerosol particle density and particle size distribution. As a result, we obtained data showing a linear relation between ion density and aersol particle density , saturation tendensy at high ion density, time variation of particle size distribution, etc. With these results, more detailed experiments will be ready.
