Optical Model Calculations of 14.6A GeV Silicon Fragmentation Cross Sections
نویسندگان
چکیده
An optical potential abrasion-ablation collision model is used to calculate hadronic dissociation cross sections for a 14.6A GeV Si beam fragmenting in aluminum, tin, and lead targets. The frictionalspectator-interaction (FSI) contributions are computed with two different formalisms for the energy-dependent mean free path. These estimates are compared with experimental data and with estimates obtained from semiempirical fragmentation models commonly used in galactic cosmic ray transport studies.

Fragmentation Cross Sections and Search ----for Nuclear Fragments with Fractional Charge in Relativistic Heavy Ion Collisions
We present measurements of fragmentation cross sections of relativistic nuclei and upper limits for the production probability of nuclear fragments with fractional charge using CR39 nuclear track detectors and an automated scanning system. The measurements of the total and partial charge changing fragmentation cross sections concern 16 GeV/nucleon oxygen ions, 14.5 GeV/nucleon silicon ions and ...

The STAR experiment at RHIC has measured a variety of inclusive hadron cross sections in p + p collisions at √ s = 200 GeV. Measurements of the differential cross section for inclusive charged pion production at mid rapidity and for inclusive neutral pion production at forward rapidity (3.0 < η < 4.2) as well as the first preliminary result from STAR for the differential cross section for inclu...

Scattering of 15N ions with the energy of Elab = 23 MeV on the CH2(Au) target is investigated. Elastic scattering of these ions in the angular range of 7°-19° was measured by employing the silicon strip detector, “LEDA”. Using the measured scattering data, deviation of ion beam, number of incident ions on the target and differential cross sections of the 12C(15N, 15N)12C elastic scattering in ...

We present new measurements of the total and partial fragmentation cross sections in the energy range 0.3 ÷ 10 A GeV of Fe, Si and C beams on polyethylene, CR39 and aluminum targets. The exposures were made at BNL, USA and HIMAC, Japan. The CR39 nuclear track detectors were used to identify the incident and survived beams and their fragments. The total fragmentation cross sections for all targe...
متن کاملNuclear transparency to intermediate-energy protons.
Nuclear transparency in the (e, e′p) reaction for 135 ≤ Tp ≤ 800 MeV is investigated using the distorted wave approximation. Calculations using densitydependent effective interactions, both empirical and theoretical, are compared with phenomenological optical potentials. We find that nuclear transparency is well correlated with proton absorption and neutron total cross sections and that calcula...
