Abstract
The fast-heavy-ion-induced neutral yield of intact molecules of the amino acid leucine has been determined as a function of the electronic stopping power, dE/dX. The experimental procedure is based on a collector method. The neutral yield varies approximately as (dE/dX. A comparison of the neutral yield to the positive and negative ion-yield dependencies on stopping power, which are weaker, reflects the different mechanisms involved in ionization and desorption.
