“…(ii) Methods of Selection Ise and Fretter (1949) and Milone, Tamburino and Villari (1950) have calculated how given close arrangements of unshielded counters in coincidence respond with regard to the position of a shower axis, and conclude that most of the recorded showers have axes close to the selecting apparatus. Milone et d. estimated that 80% of showers recorded at sea level have axes within 10 metres of the selector, but Singer (1951) has shown that this result arises on account of the numerous small showers which only have appreciable probability of operating the selector when their axes fall in the region immediately surrounding this selector.…”

The axes or cores of extensive air showers have been selected by observing in a cloud chamber cascade showers produced by a single high-energy (>5 x lo9 ev) electron or photon, and an upper limit of 5 m for the spread of such particles has been found. By placing trays of hodoscoped counters at various distances from this core selector it has been possible to determine the relation between density of ionizing particles and distance from the axis for showers of approximately 1 04-105 particles. T h e experimental arrangement and method of analysis used have certain advantages over those employed by other workers. I t is concluded that although the results of the present experiment and those of other workers are consistent with the Molikre structure function, not too much weight should be placed on this agreement.
