Abstract

The double-differential cross sections for high-energy γ-rays were measured for collisions of ³⁶Ar on C, Al, Cu, Ag, Tb, and Au at 85 MeV/nucleon. The system ³⁶Ar+ ²⁷Al has been studied in more detail in an exclusive experiment where the charged-particle multiplicity was measured in coincidence with high-energy γ-rays. A clear correlation between the hardness of the γ-spectra and the overlap distance of the two ions is observed. This correlation is interpreted as due to the spatial dependence of the Fermi momentum of the nucleons.

Hard photons and neutral pions as probes of hot and dense nuclear matter
1997, Nuclear Physics A
The dynamics of heavy-ion collisions is studied in an energy domain in the vicinity of the Fermi energy. The early history of the collision is analyzed from the theoretical and experimental point of view in which the message conveyed by bremsstrahlung photons and neutral pions is exploited. The Boltzmann-Uehling-Uhlenbeck model and the Dubna Cascade Model, both based on similar principles but each adopting different computation technics, are briefly described and their respective predictions are discussed. In particular the emission pattern of bremsstrahlung photons is discussed. The photon production has been measured in the systems ⁸⁶Kr+⁵⁸Ni at 60A MeV, ¹⁸¹Ta+¹⁹⁷Au at 40A MeV and ²⁰⁸Pb+¹⁹⁷Au at 30A MeV and energy spectra, angular distributions and two-photon correlations have been analyzed. We find that bremsstrahlung photons are emitted from two distinct sources that can be correlated with nuclear-matter density oscillations. The properties of photon emission are discussed in terms of collective properties of nuclear matter. The high energy tail of the photon spectrum is interpreted by π⁰ and Δ decay but predominantly by radiative capture of pions. The π⁰ absorption in the nuclear medium is further analyzed by examining their emission pattern.
Strong impact parameter dependence of hard photon production in intermediate energy heavy ion collisions
1993, Physics Letters B
The dependence of the high energy photon production on the impact parameter has been investigated in the reaction ¹²⁹Xe+¹⁹⁷Au at 44 MeV/u using the multidetector array MEDEA. A strong dependence of the high energy photon production probability on the impact parameter has been observed, while the slope parameter of the photon spectrum is almost constant. The data support the interpretation of the hard photon production in terms of first chance n-p collisions.
Impact parameter dependence of high energy gamma ray production in heavy-ion collisions
1992, Physics Letters B
High energy photons (E_γ⩾30 MeV) have been measured in coincidence with light particles observed in a multidetector array for the ⁴⁰Ar+⁵¹V system at a bombarding energy of $E A =65 MeV$ . Double differential cross sections were obtained as a function of the midrapidity charge representation of the centrality of the collision. The inverse slope parameter increases with centrality more strongly than predicted by a BUU model.
High-energy gamma-ray production from 284 MeV <sup>3</sup>He on nuclei
1992, Nuclear Physics, Section A
Double-differential cross sections for photons above 20 MeV were measured for the ³He+(d, C, Cu and Au) reactions at 284 MeV. The comparison of their energy spectra shows that the high-energy gamma rays are produced by the same mechanism in the very light ³He + d system and in heavier ones like ³He + (C, Cu and Au) or Xe + Sn, previously studied by the MSU group. A calculation of the ³He+(C and Au) systems at 90° in the laboratory was performed, assuming that photons are produced in first-chance nucleon-nucleon collisions and for a realistic momentum distribution of the nucleons in the ³He projectile. The results are in good agreement with the experimental data which suggests that secondary collisions are not important in the production of photons above 50 MeV for nucleus-nucleus reactions at 90 MeV/nucleon.
Photon production in heavy-ion collisions and nuclear equation of state
1991, Nuclear Physics, Section A
Photon-production cross sections in ¹²C + ¹²C, ⁴⁰Ca + ⁴⁰Ca and ⁹³Nb + ⁹³Nb collisions at E_lab = 84 and 200 MeV are calculated within the framework of the quantum molecula dynamics approach. The sensitivity of the photon-production cross section to the different types of nuclear equation of state and the momentum dependence in the in-medium NN interaction is studied in detail. Although we found some difference between the soft and hard equation of state in the calculated photon-production cross section, it is suppressed strongly by the momentum dependence in the interaction. There is a sizeable difference between the results calculated with or without taking into account the momentum dependence in the in-medium interaction. The time dependence of the production of the high-energy photons arising from incoherent pn collisions is also studied. The heavier the masses of colliding nuclei, the more number of energetic photons are produced after the system reaches the maximum density, at the expansion stage. Therefore, the photon-production data for heavy colliding nuclei might provide sc me information on the in-medium NN interaction during the time evolution of the heavy-ion reaction.
Production of energetic particles in heavy-ion collisions
1990, Physics Reports
The investigation of hot and compressed nuclear matter by means of heavy-ion collisions requires the development of probes that are sensitive to the time evolution of the nuclear phase-space density. Hard particles, such as energetic photons or mesons, which are produced during the reaction, may provide such probes. In the first part of this article we describe the time evolution of the nuclear many-body system within a nonperturbative transport approach as well as the methods employed for the evaluation of the elementary nucleon-nucleon-particle cross sections. The second part contains a description of the experimental set-ups used for the detection of hard photons in heavy-ion experiments and a discussion of the empirical systematics of data gained so far. In the third part of this article we compare the theoretical predictions for differential particle yields with the available data. Detailed comparisons are presented for hard photons at bombarding energies from 15 MeV/u to 125 MeV/u, for dileptons at 1 GeV/u and for mesons (π's, η's, K⁺'s) from 30MeV/u to 2 GeV/u. We finally discuss selection criteria for optimal probes with respect to the experimental determination of the nuclear equation of state at high densities.
