Abstract
The superposition of the wake potentials of Coulomb-exploding fragments of diatomic molecular projectiles penetrating a solid cause potential oscillations at the surface. The total electron yield per projectile serves as a signal to detect these oscillations. The plasma frequency of the solid and the wake-potential wavelength can be deduced from the data.
