The charge yield of fragments (5 <Z< 12) in the reaction 4He 4Au has been measured in the kinetic energy range 2£«He = 1.3-13.5 GeV at angles 35-135°. The cross sections of the yield were parametrized in terms of the dependence σ(Ζ) ~ Ζ ~~r. The nature of the detected minimum of the parameter r(E4He) at Еагг, & 6 GeV is discussed.
