Abstract
It is now generally agreed that the cosmic radiation consists of two groups called the soft and the hard component. This classification refers to the penetrating power of the particles in question. The soft component consists of ordinary electrons and light quanta, whereas it now seems very probable that the hard group consists of "heavy electrons". The phenomena connected with the soft component are described by the cascade theory of showers put forward by Bhabha and Heitler (1937) and Carlson and Oppenheimer (1937). It is the purpose of the present paper to work out the consequences of the theory in greater detail in order to make possible a more quantitative comparison between theory and experiment than has hitherto been possible. This is desirable for several reasons: In the first place it is important to ascertain whether the phenomena connected with the soft component can be accountant for
completely
by the cascade theory or whether some of the facts require an explanation outside the present relativistic quantum mechanics.
