Abstract
The influence of distribution of high-density (N-d) dislocations forme d due to toning at 20 K upon the superconducting transition temperatur e T-c of single-crystal Nb is studied. For uniformly distributed dislo cations in the range N-d = (6-13). 10(10) cm(-2) the experimental incr ement of T-c agrees with calculation within the model of additional el ectron attraction due to dislocation oscillations. When rotational pla sticity occurs, the sharp rise of T-c is connected with growing fields of elastic stresses.
