Measurement of the atom lifetime and the scattering length
DIRAC Collaboration, B. Adeva, L. Afanasyev +62
After having announced the statistically significant observation (5.6~) of the new exotic atom, the DIRAC experiment at the CERN proton synchrotron presents the measurement…
Observation of and atoms
DIRAC Collaboration
The observation of hydrogen-like atoms, consisting of or mesons, is presented. The atoms have been produced by 24 GeV/ protons from the CERN PS accelera…
Scintillation efficiency of liquid argon in low energy neutron-argon scattering
W. Creus, Y. Allkofer, C. Amsler +4
Experiments searching for weak interacting massive particles with noble gases such as liquid argon require very low detection thresholds for nuclear recoils. A determination of the…
First atom lifetime and scattering length measurements
B. Adeva, L. Afanasyev, Y. Allkofer +65
The results of a search for hydrogen-like atoms consisting of mesons are presented. Evidence for atom production by 24 GeV/c protons from CERN PS interacting…
Study of nuclear recoils in liquid argon with monoenergetic neutrons
C. Regenfus, Y. Allkofer, C. Amsler +4
For the development of liquid argon dark matter detectors we assembled a setup in the laboratory to scatter neutrons on a small liquid argon target. The neutrons are produced mono-…
Evidence for -atoms with DIRAC
B. Adeva, L. Afanasyev, Y. Allkofer +77
We present evidence for the first observation of electromagnetically bound -pairs (-atoms) with the DIRAC experiment at the CERN-PS. The -atoms are produced by…
