Experimental studies of the cluster structures in 9,10Be and 13,14C
have been performed. Evidence for the a+5He decay of
9Be excited states, a+6He decays of 10Be*,
a+9Be decay of 13C* and for
the decays of 14C* into a+10Be
were found. These decay processes indicate the cluster structures of the excited states.
The results are compared with recent suggestions for the presence of molecule-like
structures based upon a-particles and valence neutrons in Be
and C isotopes.
