Abstract
Studies of collisions between C-60 and K(np) Rydberg atoms with 35 les s than or equal to n less than or equal to 125 indicate that C-60 can attach very-low-energy electrons to form long-lived C-60(-) ions. The rate constant for negative ion formation is observed to be small, appr oximate to 10(-8) cm(3) s(-1), and to be independent of n pointing to s-wave capture. Possible mechanisms for this are discussed, including the formation of image-charge-bound C-60(-) ions.
