Coulomb excitation ofTe125

Abstract

The properties of the low-lying levels of '"Te were investigated by the Coulomb excitation process which was effected by bombarding a thick natural tellurium target with 9,5and 10.5-MeV 0. particles and a thick target of isotopically enriched '"Te (95%%uo) with 45-MeV ' 0 ions. Levels at 443.58, 463.39, 671.42, and 729.30 MeV were Coulomb excited and the reduced upward transition probabilities 8(E2t') (e'b) extracted from the. data were: 0.186 + 0.005, 0.158 + 0.005, 0.130 + 0.004, and 0.0059~0.0008. Angular distribution measurements were performed with 42-MeV ' 0 ions. The following results were obtained for the y rays deexciting the 443.58-(3/2') keV level: 8(408. 10)

Recent results on light nuclei production from the NA49 experiment

“…Assuming that the ratio of neutrons to protons is unity, B A is then calculated by dividing the cluster yield at a given momentum P A by the A-th power of the proton yields at P A /A. Figure 5 compares the results for B 2 and B 3 at p t = 0 from our study (red filled circles in figure 5) to experimental data from the Bevalac [18], AGS [5,19], SPS [20,21], and RHIC [22][23][24]. One concludes from this compilation that the coalescence parameters decrease only slowly with √ s NN over a broad range of collision energies: within the SPS energy range the variation of the coalescence parameter is less than 40% and 60% for B 2 and B 3 , respectively.…”

(3+1)-dimensional relativistic hydrodynamical expansion of hot and dense matter in ultra-relativistic nuclear collision

“…Hydrodynamical model is one of the established models for describing global features in the relativistic nuclear collisions as collective flow. Recently, anisotropic flow phenomena have been observed at AGS [2,3] and also at SPS [4,5,6]. Several authors have argued the relation between the behavior of the collective flow and the equation of states.…”

“…Since Danielewicz showed that elliptic flow is sensitive on nuclear equation of state in AGS energy [8], the elliptic flow is one of the hottest topics in high energy nuclear physics. The high accuracy experiments for elliptic flow have been done at AGS [2,3] and SPS [4,5,6]. Recently, using the cascade model of the ART, Li discussed the elliptic flow in the deformed uranium collisions.…”

Hadron rapidity spectra within a hybrid model

“…The solid lines are our results, the ones dashed are the results with isochronous freeze-out from [18] (b, c). Experimental points for E lab = 6 AGeV are taken from [20], for E lab = 10.7 AGeV - [21] (triangles), [22] (squares) and [23] (circles), and for E lab = 40 AGeV - [24] (squares) and [25] (the circle).…”
