Study of the N = 50 Shell Closure Close to 78

چکیده
The PARRNe (Production d’Atomes Radioactifs Riches en Neutrons) experimental program has been part of the recent R&D efforts for the design of the SPIRAL2 project at GANIL. The PARRNe2 set-up installed at IPNOrsay allows the use of the Tandem as a deuteron driver in order to produce mass separated fission fragment beams. The measured fission fragment yields proved to be high enough to undertake a series of β-decay experiments dedicated at studying the structure of proton-deficient nuclei close to N=50. We report here on two such experiments, the first being dedicated at the observation of the decay of Ga→Ge (Z=32, N=51), Ga→Ge (Z=32, N=52) and the second of the decay of Zn→Ga (Z=31, N=50) allowing for the fist time the identification of a few γ lines with transitions in the daughter nuclei thus providing the material for a preliminary glimpse of their structure.

Laparoscopic Cholecystectomy; closure versus non-closure of the fascial sheath opening of the sub-umbilical port site “10 mm”.
Background: Laparoscopic Surgery (LS) may be associated with many port site complications such as hernia, bleeding, infection, subcutaneous emphysema and ugly scars. Some of these complications are serious such as obstructed port site hernia . Rate of these complications is low depending on size and site of the port incision, type of the trocar that it is used, the condition of the patient a...

In this paper, Fe 3 O 4 @SiO 2 core/shell magnetic nanostructure has been synthesized and modified by N-(2-aminoethyl)-3-aminopropyltrimethoxysilane (AEAPTMS). Fe 3 O 4 @SiO 2 was used as a novel adsorbent for separation of hexachloroplatinic acid.X-ray diffraction (XRD), scanning electron microscopy (SEM), and FT-IR technique were used to characterize morphologies and surface te...
متن کاملIntravenous Paracetamol and Patent Ductus Arteriosus Closure
Background: Standard medical treatments for patent ductus arteriosus (PDA) closure are, including indomethacin/ibuprofen and surgical ligation. Nowadays, a new strategy to close PDA is the use of paracetamol. The present study aimed to describe the use of intravenous (IV) paracetamol for PDA closure in neonates who present a contraindication to ibuprofen or ibuprofen failure with no possibility...
