  In this work the results of the statistical analysis of the 215 stars with Ha
emission in the IC 348 cluster are presented. The sample is completed to
R<20.0.The optical radius is about 11 arcmin. The percentage of emission stars
increase from bright to fainter objects and to the range of 13.0<R-AR<19.0
reaches 80%. The ratio between WTTau and CCTau objects is 64% and 36%. The 70%
of X-ray sources are WTTau stars. The age of WTTau and CTTau objects are about
2*106 years. The age of the non emission stars with a mass less solar is about
2*106 years also, but non emission more massive objects are "older", the age of
them is about 7*106 years. The most massive stars with a low level of activity
is concentrated in a small dense central core of the cluster with a radius
about 1 arcmin, and apparently, they are generated during an earlier wave of
star formation in the cluster.
