✦ Synopsis

Caused by magnetic field H broadening 5Tri of resistive transition width has been measured for high-T e c-oriented films irradiated by He ++ ions. Found relation 8TH=B.H 2a with the coefficient B depending on fluence is interpreted in terms of flux motion and order parameter fluctuations. The 6T H anisotropy proves low sensitive to the irradiation. Decrease of the transition midpoint shift anisotropy is considered as a display of He2 anisotropy lowering.
