Notes:
A neutral C60 effusive source was assembled in a crossed molecular-beam apparatus in order to perform atom–molecule electron transfer collisions and its calibration by time-of-flight mass spectrometry. This source consists of a stainless-steel oven where the C60 sublimation takes place. Typical operation temperatures are in the range of 723 up to 888 K. Through this setup the study of the ion pair formation process K+C60→K++C60− (where K is a potassium atom) can be performed in a wide range of collision energies (10 up to 500 eV). The results show evidence of negative ion formation (being the ratio of intensities between the parent ion and fragment ions) clearly dependent on the collision energy used. © 2001 American Institute of Physics.
