The anisotropy of the first critical field Hcl is found to increase from H/c/~(0)/H~I(0)=4 to I0 on going to x=0.93 llc to. x=0.64 . For x=0.93, Hcl(0)=(950-+200)Oe, Hc1~( 0)=(230+20)Oe. For x=0.64, H/~(0)=(270-+30)Oe, .LC + Hc1(0)=(27-2)Oe. An anomalous linear T-dependence was found for H//c at low
