S. Beedoe et al., MEASUREMENT OF DIELECTRON PRODUCTION IN NIOBIUM-NIOBIUM COLLISIONS AT1.05 GEV NUCLEON/, Physical review. C. Nuclear physics, 47(6), 1993, pp. 2840-2845
A dielectron signal for pair masses greater than M(pi) is observed in
Nb+Nb collisions at 1.05 GeV/nucleon beam kinetic energy. The invarian
t mass spectrum and the associated multiplicity distribution are prese
nted. Comparisons are made with previous cross section measurements in
p+Be and Ca+Ca.
