Measuring the radii of particle unstable nuclear states and search for the signatures of alpha condensation in light nuclei

Methods of measuring the radii of unstable nuclear states based on use of diffractive and rainbow scattering were developed and applied for search of the signatures of alpha-particle condensation effects in some states of 12C, 13C and 11B near the α -thresholds. The enhancement of the nuclei radii by factor 1.2 – 1.3 relatively those in the ground states were observed.
