The alignment of energetically distinguished cores in a part of family even
ts observed with Kanbala K0-K7 emulsion chambers is analyzed,and compared w
ith the simulation results given by COSMOS and CORSIKA code. It is shown th
at the fraction of events with alignment in the experimental families incre
ases with the visible energy of families but this effect can not be explain
ed by the conventional simulations. The Criteria of identifying gamma -rays
and hadrons in the family events are also discussed.
