Fine structure of the core of extensive air showers (EAS) was studied with a device named the neon hodoscope. Considerable fluctaation of the structure was found within 3 m from the axis. In particular, those cores are noted whose lateral distribution is definitely steeper than 1/r as close as 10 cm to the axis. As the implication of these cores, it is inferred that the majority of the transferred energy may be concentrated to one or a few gamma rays (or pi /sup 0/ mesons) in some high-energy interactions of the order of 10/sup 14/ ev Three remarkable multi-core events were observed. From the energy of the separate steep core and its distance from the main axis of the EAS, the transverse momentum is estimated to be more than 5 Bev/c in each case, assuming that the separate core is due to the nuclear interaction within a few km above sea level. Frequency comparison would suggest that the large transverse momentum might be related to unusual concentration of the transferred energy into one or a few gamma rays. (auth)
