Plasmon excitation by slow ions
We present a theoretical approach to the problem of subthreshold plasmon excitation in proton-aluminum collisions. Based both on recent experimental results by Ritzau [Phys. Rev. B 59, 15506 (1999)] and on previous calculations by two of the authors, we solve the master equations and obtain the prob...

| Sumario: | We present a theoretical approach to the problem of subthreshold plasmon excitation in proton-aluminum collisions. Based both on recent experimental results by Ritzau [Phys. Rev. B 59, 15506 (1999)] and on previous calculations by two of the authors, we solve the master equations and obtain the probability of both plasmon excitation and nearly free electron excitation due to plasmon decay as functions of the projectile initial velocity. The mechanism considered for subthreshold plasmon excitation involves an intermediary fast electron as suggested by Ritzau © 2007 The American Physical Society. |
