Positron annihilation spectroscopy will often show the defects that give rise to this phenomenon as  abnormally deep vacancies, because those defects actually consist of impurities that repel conduction elec-  trons in the solid's lattice structure. This effect arises due to mutual spin flip during electron-impurity  scattering, and its namesake's original calculations predicted a divergent resistance as the thermodynamic  temperature was decreased to zero, though Anderson renormalization has yielded results in better accord  with experiment. For ten points, identify the increase in the resistivity below a certain namesake tempera-  ture on the order of 10 K [kelvins] in a crystaline substance with to trapped ferromagnetic impurities, named for a Japanese physicist.
