Inelastic cross sections at 60 and 200 GeV/nucleon are determined in a streamer chamber for 16 O on several nuclear targets. Charged particle multiplicity distributions for inelastic and central collisions are studied and compared with theoretical predictions. The inelastic cross section exhibit a geometrical dependence on nuclear radii. The multiplicity data are governed by the collision geometry. They are consistent with a picture of superposition of independent nucleon-nucleus interactions.

The scaled factorial moments, F q and fractal moments, G q have been measured and their power law variation as a function of size of the pseudorapidity interval has been studied in the central region of the pseudorapidity distribution of the produced charged particles in quasi-central and central collisions of 16 O + Ag Br at 2.1 GeV c per nucleon and 24 Mg + Ag Br at 4.5 GeV c per nucleon. The smooth spectral function f ( α q ), characterizing the fluctuation in the pseudorapidity distribution and the generalised dimensions D q have been derived from G q moments. The analyses reveal a self-similarity in multiparticle production in nucleus-nucleus interactions at an incident momentum of a few GeV/ c per nucleon. Interesting observations can be very effective in establishing multifractality in multiparticle production at this energy range.

Light fragment emission correlated with large transverse momentum protons in 94 MeV/u $^{16}$O induced reactions

Inspire Record 1389762 DOI 10.17182/hepdata.36872

Angular, multiplicity and velocity distributions as well as azimuthai asymmetries of light fragments (Z = 1 and 2) correlated with large transverse momentum protons detected at 90° have been measured in 16O + 27Al collisions at 94 MeV/u. Data are compared with a model based on the standard high-energy fireball geometry coupled with the Weisskopf theory of evaporation. Reasonable agreement is achieved with the exception of some discrepancies which could arise either from the absence of specific intermediate-energy corrections or from a non-statistical process.
