Double-differential heavy-ion production cross sections

Thick targets consisting in Al/Si alloys were bombarded with 1.0 to 5.0 MeV Ar ions. The K X-ray production cross sections were deduced from the measured yields by using the Merzbacher-Lewis formula extended to heavy ion bombardment. The density dependence on the K X-ray production cross sections of Al and Si was observed. This phenomena can be interpreted within the molecular orbital double-scattering mechanism.

Target Mass

The fragment cross sections are calculated for reactions of Ne collisions with C , Al , Cu , Sn , Ta , and Pb targets at 600 Mev/nucleon using the the isospin-dependent Boltzmann-Langevin equation. We found that the production cross sections for fragments Z = 2 to 9 are qualitatively reproduced by the present calculations except for C target. In order to understand the effects of heavy ion interaction with biomolecules well, we calculate the fragmentation cross sections for reactions of 12 C + 2 H , 12 C , 14 N , 16 O at beam energies from 50 to 100 MeV/nucleon. It is found that fragment species increase approximately with increasing target mass. The obvious increment of the fragment cross sections for heavier targets at the beam energies from 50 to 80 MeV/nucleon are shown.

Proton Induced Reactions

The production of the sigma (σ) meson is investigated in the quantum molecular dynamics model for the p+A reactions with the nuclei A being 12 C , 40 Ca and 208 Pb at the incident proton energies Ep = 1.50 GeV . The simulation results indicates a distinctive A dependence of the sigma production, that is, the increase of A is followed by an increase of the production cross-sections. The σ meson production in proton induced reactions is strongly medium-dependent, and the produced σ mesons decaying in a denser medium experience a stronger mass shift towards lower masses. This mass shift is an experimentally accessible observable in the final state pion pairs which did not suffer reabsorption by the surrounding nucleons. It is pointed out that the ratio of the simulation results of measurable σ mesons (in the form of two pions) cross-sections as a function of the sigma invariant-mass from various reactions opens the possibility to address experimentally the mass shift of the σ in a dense nuclear environment.
