A delayed ionisation experiment has been carried out on laser excited C70 molecules. Ions and electrons are detected in coincidence to distinguish the ionisation of C70 from that of C68 molecules created by the dominant process, emission of C2. From

We have measured the kinetic energy released in the unimolecular dissociation of fullerene ions, Cn+ --> C(n-2)+ + C2, for sizes 42 < or = n < or = 90. A three-sector-field mass spectrometer equipped with two electric sectors has been used in order t

We have studied experimentally the collisional charge transfer between a neutral atom and a multicharged metal-atom cluster. The charge transfer cross section measured for Na 31 + + + Cs is in the range of 400 A2. The time-of-flight mass analysis of

Amino acid clusters have been studied by several groups and most notably magic number clusters and chiral recognition have been reported. In this work, we have studied the formation of amino acid clusters by electrospray ionization (ESI) and their st
