Atomic spectroscopy at Orsay

The ALTO Project at IPN Orsay

In order to probe neutron rich radioactive noble gases produced by photo-fission, a PARRNe1 experiment (Production d’Atomes Radioactifs Riches en Neutrons) has been carried out at CERN. The incident electron beam of 50 MeV was delivered by the LIL machine: LEP Injector Linac. The experiment allowed to compare under the same conditions two production methods of radioactive noble gases: fission i...

Indirect Determination of Ascorbic Acid by Atomic Absorption Spectroscopy

A new and simple method followed by atomic absorption spectrometry has been developedfor indirect determination of ascorbic acid (AA). The proposed method was based on the oxidationof AA to dehydroascorbic acid with Cu2+cation(200mgL-1)in an ammonium thiocyanatesolution atpH2.4. AA reduces Cu2+to Cu+followed by the precipitation of Cu+ with SCN-. Then, the excess ofCu2+in the solution was measu...

The Alto Tandem and Isol Facility at IPN Orsay

Alto is an infrastructure for experimental nuclear physics in France that comprises both an on-line isotope-separation facility based on the photofission of uranium and a stableion beam facility based on a 14.5-MV tandem accelerator. The isotope-separation on-line section of Alto is dedicated to the production of neutron-rich radioactive ion beams (RIB) from the interaction of the γ-flux induce...

LPT–Orsay 01–46 PHOTOPRODUCTION OF PROMPT PHOTONS AT NLOa

A numerical program to calculate the photoproduction of prompt photons is presented. The code includes full next-to-leading order corrections to all subprocesses. The results are compared to recent ZEUS data.
