Scaling properties of light-cluster production
Z. Chajecki, M. Youngs, D. D. S. Coupland +27
We show that ratios of light-particle energy spectra display scaling properties that can be accu- rately described by effective local chemical potentials. This demonstrates the equ…
Neutron recognition in the LAND detector for large neutron multiplicity
P. Pawłowski, J. Brzychczyk, Y. Leifels +61
The performance of the LAND neutron detector is studied. Using an event-mixing technique based on one-neutron data obtained in the S107 experiment at the GSI laboratory, we test th…
Time-of-flight mass measurements for nuclear processes in neutron star crusts
A. Estrade, M. Matos, H. Schatz +23
The location of electron capture heat sources in the crust of accreting neutron stars depends on the masses of extremely neutron-rich nuclei. We present first results from a new im…
Angular Dependence in Proton-Proton Correlation Functions in Central and Reactions
V. Henzl, M. A. Kilburn, Z. Chajecki +21
The angular dependence of proton-proton correlation functions is studied in central and nuclear reactions at E=80 MeV/A. Measurements were perfo…
Ground-state proton decay of 69Br and implications for the rp-process 68Se waiting-point
A M Rogers, W G Lynch, M A Famiano +19
The first direct measurement of the proton separation energy, Sp, for the proton-unbound nucleus 69Br is reported. Of interest is the exponential dependence of the 2p-capture rate…
Isospin dependent multifragmentation of relativistic projectiles
R. Ogul, A. S. Botvina, U. Atav +57
The N/Z dependence of projectile fragmentation at relativistic energies has been studied with the ALADIN forward spectrometer at the GSI Schwerionen Synchrotron (SIS). Stable and r…
Tracing a phase transition with fluctuations of the largest fragment size: Statistical multifragmentation models and the ALADIN S254 data
T. Pietrzak, P. Adrich, T. Aumann +54
A phase transition signature associated with cumulants of the largest fragment size distribution has been identified in statistical multifragmentation models and examined in analys…
Isotopic Dependence of the Caloric Curve
The ALADIN2000 Collaboration, W. Trautmann, P. Adrich +54
Isotopic effects in projectile fragmentation at relativistic energies have been studied with the ALADIN forward spectrometer at SIS. Stable and radioactive Sn and La beams with an…
Isotopic Dependence of the Nuclear Caloric Curve
The ALADIN2000 Collaboration, C. Sfienti, P. Adrich +54
The A/Z dependence of projectile fragmentation at relativistic energies has been studied with the ALADIN forward spectrometer at SIS. A stable beam of 124Sn and radioactive beams o…
Mechanisms in knockout reactions
D. Bazin, R. J. Charity, R. T. de Souza +17
We report on the first detailed study of the mechanisms involved in knockout reactions, via a coincidence measurement of the residue and fast proton in one-proton knockout reaction…
N/Z Dependence of Projectile Fragmentation
W. Trautmann, P. Adrich, T. Aumann +53
The N/Z dependence of projectile fragmentation at relativistic energies has been studied in a recent experiment at the GSI laboratory with the ALADiN forward spectrometer coupled t…
Fragmentation cross-sections and binding energies of neutron-rich nuclei
M. B. Tsang, W. G. Lynch, W. A. Friedman +18
An exponential dependence of the fragmentation cross-section on the average binding energy is observed and reproduced with a statistical model. The observed functional dependence i…
Discriminant Analysis and Secondary-Beam Charge Recognition
J. Lukasik, P. Adrich, T. Aumann +53
The discriminant-analysis method has been applied to optimize the exotic-beam charge recognition in a projectile fragmentation experiment. The experiment was carried out at the GSI…
TOF-Brho Mass Measurements of Very Exotic Nuclides for Astrophysical Calculations at the NSCL
M Matos, A Estrade, M Amthor +17
Atomic masses play a crucial role in many nuclear astrophysics calculations. The lack of experimental values for relevant exotic nuclides triggered a rapid development of new mass…
Projectile Fragmentation of Kr at 64 MeV/nucleon
M. Mocko, M. B. Tsang, Z. Y. Sun +18
We measured fragmentation cross sections produced using the primary beam of Kr at 64 MeV/nucleon on Be and Ta targets. The cross sections were obtained by integr…
Extrapolation of neutron-rich isotope cross-sections from projectile fragmentation
M. Mocko, M. B. Tsang, Z. Y. Sun +13
Using the measured fragmentation cross sections produced from the 48Ca and 64Ni beams at 140 MeV per nucleon on 9Be and 181Ta targets, we find that the cross sections of unmeasured…
