Analysis of charged particle emission sources and coalescence in E/A = 61 MeV 36^{36}Ar + 27^{27}Al, 112^{112}Sn and 124^{124}Sn collisions

Single-particle kinetic energy spectra and two-particle small angle correlations of protons ($p$), deuterons ($d$) and tritons ($t$) have been measured simultaneously in 61A MeV $^{36}$Ar + $^{27}$Al, $^{112}$Sn and $^{124}$Sn collisions. Characteristics of the emission sources have been derived from a ``source identification plot'' ($\beta_{source}$--$E_{CM}$ plot), constructed from the single-particle invariant spectra, and compared to the complementary results from two-particle correlation functions. Furthermore, the source identification plot has been used to determine the conditions when the coalescence mechanism can be applied for composite particles. In our data, this is the case only for the Ar + Al reaction, where $p$, $d$ and $t$ are found to originate from a common source of emission (from the overlap region between target and projectile). In this case, the coalescence model parameter, $\tilde{p}_0$ -- the radius of the complex particle emission source in momentum space, has been analyzed.Comment: 20 pages, 5 figures, submitted to Nuclear Physics

The European Large Area Iso Survey: 90 micron number counts.

The European Large Area ISO Survey (ELAIS) was the largest single Open Time project conducted by ISO, mapping an area of 12 square degrees at 15μm with ISO-CAM and at 90μ with ISOPHOT. We first present the data analysis of the 90 μm survey. We show comparisons with model prediction for standard stars and with COBE/DIRBE for surface brightnesses of individual ELAIS fields and with the IRAS FSC catalog for 35 sources in common. The large number of rasters necessary to cover the wide ELAIS areas allows to compute a relative uncertainty for the calibration based on the FCS of typically 7%. From the comparison with standard stars model predictions, the absolute calibration is shown to be better than 15%. The survey is 1.5 order of magnitude deeper than the IRAS 100μ m survey and is expected to provide constraints on the formation and evolution of galaxies. Finally, we present 90 μm number counts from a reliable subset of the detected sources. ELAIS number counts are compared to the evolutionnary models of Guiderdoni (1998) and Rowan-Robinson (2001)
