The particle-induced depression of the superconducting critical temperature {ital T}{sub {ital c}} of YBa{sub 2}Cu{sub 3}O{sub 7{minus}{delta}} is shown to be directly proportional, over seven orders of magnitude, to the nonionizing energy deposited in the lattice by primary knock-on atoms displaced by incident electrons, protons, and heavy ions. It is concluded that {Delta}{ital T}{sub {ital c}} is proportional only to the average number of defects produced and can therefore be predicted for any particle, energy, and fluence from a calculation of the nonionizing energy loss.
