Differential Double Capture Cross Sections In P+He Collisions, Michael Schulz, T. Vajnai, J. A. Brand

We have measured differential double capture cross sections for 15 to 150 keV p+He collisions. We also analyzed differential double to single capture ratios, where we find pronounced peak structures. An explanation of these structures probably requires a quantum-mechanical description of elastic scattering between the projectile and the target nucleus. Strong final-state correlations have a large effect on the magnitude of the double capture cross sections


Kinematically Complete Experiment On Transfer Excitation In Intermediate-Energy P + He Collisions, Ahmad Hasan, B. Tooke, M. Zapukhlyak, T. Kirchner, Michael Schulz Jan 2006

Kinematically Complete Experiment On Transfer Excitation In Intermediate-Energy P + He Collisions, Ahmad Hasan, B. Tooke, M. Zapukhlyak, T. Kirchner, Michael Schulz

We have performed a kinematically complete experiment on transfer excitation in intermediate-energy proton-helium collisions. The differential cross sections were compared to double excitation data and a nonperturbative time-dependent calculation. This comparison reveals the importance of dynamic couplings between the motion of the heavy nuclei and electronic transitions and/or electron-electron correlation effects.
