Fragmentation cross sections of protonated water clusters.
We have measured fragmentation cross sections of protonated water cluster cations (H(2)O)(n=30-50)H(+) by collision with water molecules. The clusters have well-defined sizes and internal energies. The collision energy has been varied from 0.5 to 300 eV. We also performed the same measurements on deuterated water clusters (D(2)O)(n=5-45)D(+) colliding with deuterated water molecules. The main f...
متن کاملImproved Empirical Parametrization of Fragmentation Cross Sections
A useful tool to predict production cross sections of exotic nuclei in high-energy fragmentation reactions is a universal analytical formula called EPAX [1, 2]. This formula allows to calculate the yields from fragmenting all non-fissile projectiles in the range of projectile masses between about 40 to 209. The cross sections are assumed to be energy-independent and appear to be reliable at inc...
متن کاملFragmentation Cross Sections and Search ----for Nuclear Fragments with Fractional Charge in Relativistic Heavy Ion Collisions
We present measurements of fragmentation cross sections of relativistic nuclei and upper limits for the production probability of nuclear fragments with fractional charge using CR39 nuclear track detectors and an automated scanning system. The measurements of the total and partial charge changing fragmentation cross sections concern 16 GeV/nucleon oxygen ions, 14.5 GeV/nucleon silicon ions and ...
متن کاملCharge transfer and fragmentation in cluster–atom collisions
Charge transfer and fragmentation in collisions of sodium cluster ions with caesium atoms have been investigated theoretically within a microscopic framework called Non-adiabatic Quantum Molecular Dynamics. To illustrate the complexity of non-adiabatic cluster collisions, in particular the interplay between charge transfer and fragmentation, Na4 (2.7 keV) + Cs collisions are studied in detail w...
متن کاملInfrared spectra of protonated polycyclic aromatic hydrocarbon molecules: azulene.
The infrared (IR) spectrum of protonated azulene (AzuH(+), C(10)H(9)(+)) has been measured in the fingerprint range (600-1800 cm(-1)) by means of IR multiple photon dissociation (IRMPD) spectroscopy in a Fourier transform ion cyclotron resonance mass spectrometer equipped with an electrospray ionization source using a free electron laser. The potential energy surface of AzuH(+) has been charact...
