Abstract
The observation of muons in EAS relevant to the age parameter which has been determined from a lateral density distribution of electrons has been carried out by means of a neon hodoscope array at Mt. Norikura (2770m.a.s.l.). As a result, it was found that there is a strong correlation between lateral distributions of electrons and of muons. The lateral distribution of muons as a power function of the distance r from the core axis has the exponent which varies from -0.8 to -1.7 with the change of age parameter of EAS. The empirical distribution function of muons with various age parameter can be expressed as; Δ µ( r , N e , s )= f ( s ) r - g ( s ) e -( r /250) ( N e /10 6 ) 0.8 w h e r e f(s)=3×10^4exp (-7.26s) a n d g(s)=8.0exp (-2.0s).
