On the Charge-State Dependence of Secondary Ion Emission from Phenylalanine

Influence of the charge state of 1.16 MeV/u incident ions on the desorption process

“…Measurements have been made over a large mass range (N to U), as well as some measurements at high energy (up to 5 Mev/u) for projectiles of intermediate mass. These have yielded fairly complete results on the behaviour of the secondary ion yields as a function of the primary ion velocity [11]. The desorption processes depend in a complex way on the dE/dx of the ion in the material and thus on the charge of the incident ion.…”

“…This machine can accelerate a large range of ions (from 12C to 109 Ag or 134Xe) and its energy of Article published online by EDP Sciences and available at http://dx.doi.org/10.1051/jphys:01987004802026100 1.16 Mev/u is close to the value where the desorption yield is maximum [5,9,11]. Experiments complementary to the previous measurements [10] have therefore been undertaken at Orsay, in collaboration with the Darmstadt group.…”
