Charge-exchange (d,2He) reactions in inverse kinematics at
intermediate energies are a very promising method to investigate the
Gamow-Teller transition strength in unstable nuclei. A simulation and analysis
software based on the ATTPCROOT package was developed to
study these type of reactions with the active-target time projection chamber
(AT-TPC). The simulation routines provide a realistic detector response that
can be used to understand and benchmark experimental data. Analysis tools and
correction routines can be developed and tested from simulations in
ATTPCROOT, because they are processed in the same way as the
real data. In particular, we study the feasibility of using coincidences with
beam-like particles to unambiguously identify the (d,2He)
reaction channel, and to develop a kinematic fitting routine for future
applications. More technically, the impact of space-charge effects in the track
reconstruction, and a possible correction method are investigated in detail.
This analysis and simulation package constitutes an essential part of the
software development for the fast-beams program with the AT-TPC
