We report the experimental observation of a light polarization rotation in vacuum presence transverse magnetic field. Assuming that data distribution is Gaussian, average measured (3.9 +/- 0.5) x 10(-12) rad/pass, at 5 T with 44 000 passes through 1 m long magnet, lambda = 1064 nm. The relevance this result terms existence light, neutral, spin-zero particle discussed.
In 2006 the PVLAS collaboration reported observation of an optical rotation generated in vacuum by a magnetic field. To further check against possible instrumental artifacts, several upgrades to apparatus have been made during past year. Two data taking runs, at wavelength 1064 nm, performed new configuration with field strengths 2.3 and 5 T. The T value was chosen order avoid stray fields. observations do not show presence signal down levels...
The authors have built a small animal Positron Emission Tomograph (YAP-PET) based on four matrices of 400 YAP:Ce finger crystals (2/spl times/2/spl times/30 mm/sup 3/ each) coupled to Position Sensitive PhotoMultiplier Hamamatsu R2486-06. system consists detectors rotating gantry with variable diameter from 10 and 25 cm. read-out data acquisition are handled by NIM-CAMAC standard electronics. tomograph has total Field Of View (FOV) 4/spl times/4/spl times/4 cm/sup that is appropriate for...
Experimental bounds on induced vacuum magnetic birefringence can be used to improve present photon-photon scattering limits in the electronvolt energy range.

At the Department of Physics University Pisa, Italy, a new and fully engineered version YAP-(S)PET small animal scanner has been recently installed. The is able to perform both PET SPECT studies on animals. made up four heads: each one composed 4/spl times/4 cm/sup 2/ YAlO/sub 3/:Ce (or YAP:Ce) matrix 20/spl times/20 elements, 2/spl times/2/spl times/25 mm/sup 3/ each, coupled Position Sensitive Photomultiplier (PS-PMT) (Hamamatsu R2486). modules are positioned rotating gantry. switching...
The frequency noise properties of commercial distributed feedback quantum cascade lasers emitting in the 4.6 μm range and operated cw mode near room temperature (277 K) are presented. measured power spectral density reveals a flicker dropping down to very low level <100 Hz(2)/Hz at 10 MHz Fourier is globally factor 100 lower than data recently reported for similar laser cryogenic temperature. This makes our good candidate realization mid-IR ultranarrow linewidth reference.
The machine described in this document is an advanced Source of up to 20 MeV Gamma Rays based on Compton back-scattering, i.e. collision intense high power laser beam and a brightness electron with maximum kinetic energy about 720 MeV. Fully equipped collimation characterization systems, order generate, form fully measure the physical characteristics produced Ray beam. quality, phase space density, two colliding beams will be such that emitted ray characterized by tunability, spectral...
JWH-018 and AKB48 are two synthetic cannabinoids (SCBs) belonging to different structural classes illegally marketed as incense, herbal preparations, or chemical supply for theirs psychoactive cannabis-like effects. Clinical reports from emergency room reported psychomotor agitation one of the most frequent effects in people assuming SCBs. This study aimed investigate psychostimulant properties male CD-1 mice compare their behavioral biochemical with those caused by cocaine amphetamine. In...
We report on light shift and broadening in the atomic-motion-induced Ramsey narrowing of dark resonances prepared alkali-metal vapors contained wall-coated cells without buffer gas. The is due to free motion polarized atomic spins out optical interaction region before spin relaxation. As a consequence this effect, we observe resonance linewidth as well reduction ground states' when volume decreases at constant intensity. results can be intuitively interpreted dilution intensity effect...
The authors have successfully built and characterised a small animal PET based on 4 rotating detectors with spatial resolution <2 mm over its field of view sensitivity 640 cps//spl mu/Ci at the centre. scanner is four matrices 400 YAP:Ce finger crystals (2/spl times/2/spl times/30 mm/sup 3/ each) coupled to Position Sensitive PhotoMultipliers (Hamamatsu R2486-06.) now applied two high collimators opposite detectors, hence realising an integrated PET-SPECT for animals. are made lead 20 long,...
A new scintillation detector system has been designed for application in high resolution positron emission tomography (PET). The is a bundle of small YAlO/sub 3/:Ce (YAP) crystals closely packed (0.2/spl times/0.2/spl times/3.0 cm/sup 3/), coupled to position sensitive photomultiplier tube (PSPMT). preliminary results obtained spatial resolution, time energy and efficiency 2 such detectors working coincidence are presented.

At Legnaro laboratories of the Italian National Institute for Nuclear Physics (INFN), a feasibility study has started since 2011 related to accelerated-based direct production by 100 Mo(p,2n) reaction. Both theoretical investigations and some recent preliminary irradiation tests on Mo-enriched samples have pointed out that both / ratio specific activity will be basically different in final accelerator-produced Tc with respect generator-produced one, which might affect radiopharmaceutical...
Evaluation of the radioisotopic purity technetium-99m (99mTc) produced in GBq amounts by proton bombardment enriched molibdenum-100 (100Mo) metallic targets at low energies (i.e. within 15-20 MeV) is conducted. This energy range was chosen since it easily achievable many conventional medical cyclotrons already available nuclear medicine departments hospitals. The main motivation for such a study framework research activities international level that have been conducted over last few years to...
