The three bunch dimensions (transverse sizes along with bunch length) was measured against bunch current to detect the energy spread growth. Emmitance growth due to multiple intrabeam scattering was observed at bunch current below turbulence bunch lengthening threshold. The thresholds of these proceses was used to estimate values of longitudinal impedance. Obtained values in a good agreement with predictions.
