Tanaka, M

The total neutral energy spectra, E/sub TOT//sup 0/ = ..sigma../sub i/ epsilon/sub i//sup 0/, have been measured in the central region of ..cap alpha cap alpha.., dd and pp interactions at ..sqrt..s/sub NN/ = 31 GeV with an electromagnetic calorimeter covering 2..pi.. in azimuth. The data were collected in the light-ion run at the CERN ISR during August 1983. The cross section ratio of the ..cap alpha cap alpha.. to the pp interactions increases rapidly with E/TOT//sup 0/ from 7 to 10/sup 5/ in the range 1.5 < E/sub TOT//sup 0/ < 19 GeV. The data are compared with a simple model of simultaneous multiple nucleon-nucleon collisions.
