A measurement of alpha-alpha elastic scattering at the CERN ISR

1985

Abstract We present measurements of the αα elastic scattering differential cross section at √ s = 126 GeV in the range 0.05 ⩽ ‖ t ‖ c ) 2 . The data give an improved definition of the first cross section minimum at ‖ t ‖ = 0.098 (GeV/ c ) 2 and are consistent with theotheoretical models of nucleus-nucleus scattering. The αα total cross section obtained by extrapolation to the optical point is 280 ± 70 mb.
