Inspire Record 1389455 DOI 10.17182/hepdata.27780

Nuclear reactions induced in silver by 25.2 GeV 12C ions have been studied by the activation technique and compared with those induced by 300 GeV protons.

Table 1

Two sets of data were normalized to each other by requiring that the weighted mean of 15 cross section ratios for products in A = 66 - 90 region be equal to unity. SIG(C=PROTON) stands for the reacion with proton beam (PLAB=300 GeV) with the same final state.

Peripheral collisions of 40 MeV/u $^{14}$N with a $^{197}$Au target

Pruneau, C. ; Potvin, L. ; Roy, R. ; et al.

Nucl.Phys.A 500 (1989) 168-194, 1989.

A 32-phoswich detector array has been used in conjunction with two Si-telescopes to detect, in coincidence, light and projectile-like fragments produced in the reaction 14N + 197Au at 560 MeV. Inclusive and semi-exclusive cross sections are given. Angular correlations and invariant cross-section velocity distributions of light particles in coincidence with projectile-like fragments are used to deduce the dominant reaction mechanisms. The transfer of nucleons to the target and sequential breakup of the quasi-projectile with or without pickup of target nucleons are clearly seen. Some evidence is found for a prompt breakup of the projectile into 10B + α followed by a dissipative interaction of the heavy fragment with the target.

Measurements of light nuclei production in 11.5-A-GeV/c Au + Pb heavy-ion collisions.

The E864 collaboration Armstrong, T.A. ; Barish, K.N. ; Batsouli, S. ; et al.

Phys.Rev.C 61 (2000) 064908, 2000.

Inspire Record 525664 DOI 10.17182/hepdata.25465

We report on measurements by the E864 experiment at the BNL-AGS of the yields of light nuclei in collisions of Au(197) with beam momentum of 11.5 A GeV/c on targets of Pb(208) and Pt(197). The yields are reported for nuclei with baryon number A=1 up to A=7, and typically cover a rapidity range from y(cm) to y(cm)+1 and a transverse momentum range of approximately 0.1 < p(T)/A < 0.5 GeV/c. We calculate coalescence scale factors B(A) from which we extract model dependent source dimensions and collective flow velocities. We also examine the dependences of the yields on baryon number, spin, and isospin of the produced nuclei.

Strangelet search and light nucleus production in relativistic Si + Pt and Au + Pt collisions

The E886 collaboration Rusek, A. ; Bassalleck, B. ; Berdoz, A. ; et al.

Phys.Rev.C 54 (1996) R15-R19, 1996.

Inspire Record 429741 DOI 10.17182/hepdata.25801

A strangelet search in Si+Pt and Au+Pt collisions at alternating-gradient synchrotron (AGS) energies, using a focusing spectrometer, sensitive to mass per charge of 3-14 GeV/c2 was conducted during the 1992 and 1993 heavy ion runs at the AGS. The null results thereof are presented as upper limits on the invariant production cross section, in the range of 10−5-10−4 mb c3/GeV2, and model dependent sensitivity limits in the range of 10−7-10−5 per collision. Measurements of the production cross sections of several nonstrange nuclear systems, from p to Be7 and Li8, the background of the strangelet search, are also presented.
