| Abstract: | Double-differential emission distributions W(B,Ex) in angle 8 and energy Ex of prompt x-rays released in binary and light charged particle (LCP) accompanied fission of 252-Cf have been measured. The x-ray anisotropies are rather similar for both fission modes but the shapes of the angular distributions differ considerably. The maxima of the angular distributions are shifted from zero degree in the binary mode to 8≈20.30 deg. in the LCPac. fission. This behaviour may be understood as an influence of the α-particle (predominantly emitted in equatorial direction) on the alignment of angular momenta produced in bending modes. |
