Exclusive measurements on $^{56}$Fe+p at 1 A Gev with the SPALADIN setup at GSI

Abstract : A new type of spallation experiments has been carried out at GSI, Darmstadt (Germany) in order to understand the spallation mechanism in greater details. These experiments use the inverse-kinematics technique where the ion beam is directed onto a liquid Hydrogen target, allowing the detection of heavy spallation residues in coincidence with low center-of-mass energy light particles. The setup is based on A Large Acceptance DIpole magNet (ALADIN) coupled with a multitrack Time Projection Chamber (TPC), a hodoscope and a neutron detector. First, data on $^{56}$Fe+p at 1 A GeV were taken in February 2004. In the on-going analysis, isotopic cross-sections have been determined and compared to data taken at the FRagment Separator in GSI. Mean values and width of residue velocity distributions have also been obtained as well as Helium production cross-section. First, coincidence data are being analyzed.
