摘要
-The probabilities P<sub>NCNE</sub> of non-equilibration component of tilting spinmode have been extracted from the experimental fragment anisotropies for thesystems of <sup>16</sup>O+<sup>232</sup>Th,<sup>19</sup>F+<sup>232</sup>Th,and <sup>16</sup>O+<sup>238</sup>U.It is found that as a function ofB<sub>f</sub>（〈L〉）/T<sub>sad</sub>,the values of P<sub>NCNF</sub> observed experimentally and expected on the ba-sis of fission before equilibration model have opposite trends.
