Abstract
Using an apparatus previously described measurements of the number of gapsn total lenght of gapsx mean gap lenghtw = x/n and number of « long » gapsn ε were made on a large number of traks Proton πmeson and μmeson traks coming to rest in the stack of pellicles the no 29 stack of Sardinian Expedition 1953 were employed A rather large velocity interval has been investigated 0v/c080 Our experimental results have been compared with the different theories which have been proposed to describe the formation of traks of ionizing particles in nuclear emulsions The problem of choosing the parameter which must be measured in the different velocity intervals in order to obtain the best value of the mass is discussed It turns out that the best parameters are in the near minimum regionw and in the «clogged » regionx
