Search for antihelium in cosmic rays

The Alpha Magnetic Spectrometer (AMS) was flown on the space shuttleDiscovery during flight STS-91 in a 51.7 degree orbit at altitudes between 320and 390 km. A total of 2.86 * 10^6 helium nuclei were observed in the rigidityrange 1 to 140 GV. No antihelium nuclei were detected at any rigidity. An up...

description The Alpha Magnetic Spectrometer (AMS) was flown on the space shuttleDiscovery during flight STS-91 in a 51.7 degree orbit at altitudes between 320and 390 km. A total of 2.86 * 10^6 helium nuclei were observed in the rigidityrange 1 to 140 GV. No antihelium nuclei were detected at any rigidity. An upperlimit on the flux ratio of antihelium to helium of < 1.1 * 10^-6 is obtained.
