The gamma decay from Coulomb excitation of 68Ni at 600 MeV/nucleon on a Au target was measured using the RISING setup fragment separator GSI. beam produced by fragmentation reaction 86Kr 900 9Be and selected separator. rays were with HPGe detectors forward angles BaF2 scintillators backward angles. spectra show peak centered approximately 11 MeV, whose intensity can be explained in terms an enhanced strength dipole response function (pygmy resonance). Such pygmy structure has been predicted...
In this paper, a time-integrated search for point sources of cosmic neutrinos is presented using the data collected from 2007 to 2010 by ANTARES neutrino telescope. No statistically significant signal has been found and upper limits on flux have obtained. Assuming an E−2ν spectrum, these are at 1–10 ×10−8 GeV cm−2 s−1 declinations ranging −90° 40°. Limits specific models RX J1713.7−3946 Vela X, which include information source morphology also given.
The ANTARES neutrino telescope, located 40km off the coast of Toulon in Mediterranean Sea at a mooring depth about 2475m, consists twelve detection lines equipped typically with 25 storeys. Every storey carries three optical modules that detect Cherenkov light induced by charged secondary particles (typically muons) coming from interactions. As these are flexible structures fixed to sea bed and held taut buoy, currents cause move storeys rotate. knowledge position precision better than 10cm...
The data taken with the ANTARES neutrino telescope from 2007 to 2010, a total live time of 863 days, are used measure oscillation parameters atmospheric neutrinos. Muon tracks reconstructed energies as low 20 GeV. Neutrino oscillations will cause suppression vertical upgoing muon neutrinos such crossing Earth. determining extracted by fitting event rate function ratio estimated energy and flight path through Measurement contours in two-flavour approximation derived. Assuming maximal mixing,...
The deep ocean is the largest and least known ecosystem on Earth. It hosts numerous pelagic organisms, most of which are able to emit light. Here we present a unique data set consisting 2.5-year long record light emission by deep-sea measured from December 2007 June 2010 at ANTARES underwater neutrino telescope in NW Mediterranean Sea, jointly with synchronous hydrological records. This longest continuous time-series bioluminescence ever recorded. Our reveals several weeks long, seasonal...
Results are presented of a search for cosmic sources high energy neutrinos with the ANTARES neutrino telescope. The data were collected during 2007 and 2008 using detector configurations containing between 5 12 detection lines. integrated live time analyzed is 304 days. Muon tracks reconstructed likelihood-based algorithm. Studies timing indicate median angular resolution 0.5 +/- 0.1 degrees. flux sensitivity 7.5 x 10-8 ~ (E/GeV)^-2 GeV^-1 s^-1 cm^-2 part sky that always visible (declination...
We present the results of first search for gravitational wave bursts associated with high energy neutrinos. Together, these messengers could reveal new, hidden sources that are not observed by conventional photon astronomy, particularly at energy. Our uses neutrinos detected underwater neutrino telescope ANTARES in its 5 line configuration during period January - September 2007, which coincided fifth and science runs LIGO Virgo, respectively. The LIGO-Virgo data were analysed candidate...
A search for neutrino-induced muons in correlation with a selection of 40 gamma-ray bursts that occurred 2007 has been performed the ANTARES neutrino telescope. During period, detector consisted 5 detection lines. The telescope is sensitive to TeV–PeV neutrinos are predicted from bursts. No events were found prompt photon emission and upper limits have placed on flux fluence different models.
The total absorption spectrometer installed at the GSI on-line mass separator was used to study $\ensuremath{\beta}$-decay of ${J}^{\ensuremath{\pi}}={9}^{+}$ isomer in $^{70}\mathrm{Br}$. decay energy ${Q}_{EC}$ found be $12.19(\ifmmode\pm\else\textpm\fi{}{7}_{\mathrm{stat}}\ifmmode\pm\else\textpm\fi{}{4}_{\mathrm{sys}})\phantom{\rule{0.3em}{0ex}}\mathrm{MeV}$. By comparing this value with estimated for ground state $^{70}\mathrm{Br}$, excitation is...
A multimessenger analysis optimized for a correlation of arrival directions ultra-high energy cosmic rays (UHECRs) and neutrinos is presented applied to 2190 neutrino candidate events detected in 2007–2008 by the ANTARES telescope 69 UHECRs observed Pierre Auger Observatory between 2004 January 1 2009 December 31. No significant observed. Assuming an equal flux (E−2 spectrum) from all UHECR directions, 90% CL upper limit on 5.0 × 10−8 GeV cm−2 s−1 per source derived.
