Resumen:
Electron capture reactions for 3He2+ collisions on
He at impact energies in the range 40 keV-300 keV have been studied
using the Cold Target Recoil-Ion Momentum Spectroscopy setup which has
recently became operational at the Centro Atomico Bariloche.
State-selective charge exchange cross sections were obtained and in this
work we present recoil-ion transverse momentum distributions. For
targets with residual thermal motion, we show that the implementation of
a back-projection algorithm based on the transverse momentum
distribution component along a direction perpendicular to the jet
direction provides results in agreement with those obtained by using
previously cooled targets. Present results nicely fit the gaps in the
datasets already published by other laboratories and are found to be in
good agreement with classical trajectory Monte Carlo simulations.
