We propose and discuss the development of a new photo-detector to be employed in underwater neutrino detectors where large detection area and good background suppression are required. The design includes a position-sensitive hemispherical photomultiplier coupled to a direction-sensitive light-guide system.

Differential capture View the MathML source and View the MathML source cross sections have been measured at excitation energies between 17 and 41 MeV in 17F and 26 and 39 MeV in 17O at several angles in the 35°–135° interval. The (p, γo) data show, besides a direct capture term, the excitation of giant dipole resonances based on excited states...

The Bloom-Gilman local duality of the inelastic structure function of the proton, the deuteron, and light complex nuclei is investigated using available experimental data in the squared four-momentum transfer range from 0.3 to 5 (GeV/c)2. The results of our analysis suggest that the onset of the Bloom-Gilman local duality is anticipated in...

Differential capture 12C(p, γ)13N and 11B(d, γ)13C cross sections have been measured in the excitation energy region between 20 and 45 MeV in 13N and 25 and 42 MeV in 13C. Angular distributions are given for the pγ channel at each energy, while the dγ excitation function has been measured at 60°. The pγ0 data show, besides a direct capture...

We describe an event generator that reproduces the photon-nucleon interaction from the pion threshold up to 4 GeV accounting to a large extent for the total photoabsorption cross section. Many reaction channels on the nucleon have been considered: namely single pion production, eta production, multipion production and some hyperon production...

An anticoincidence, high-efficiency, BGO gamma spectrometer, designed for energies in the range 10–100 MeV, is presented. The detector performances, measured with photons produced in several capture reactions, are reported and compared with the predictions of a Monte Carlo code, and with performances of a NaI spectrometer of very similar design.

The2H(d, gamma)4He differential cross section was measured at deuteron laboratory energies of 20, 24, and 28 MeV between thetacm=45° and thetacm=135°. AtE d =28 MeV a complete angular distribution was determined and fitted with Legendre polynomials. The ratioR=dsgr/dOHgr (thetacm=90°)/dsgr/dOHgr (thetacm=135°) was measured for each deuteron energy.

The WhaleSafe project aims at preserving both sperm whales and boats from unwished collision in Santuario Pelagos, close to Savona (Italy). The system is made of 2 mother buoys, each one connected with its daughter through a data cable. The mother buoys provide power from the Sun and wind to their daughters who have 4 hydrophones and an...

In WhaleSafe project the data collected from 2 couples of buoys with 4 hydrophones will be analysed to estimate TDOA in the signal emitted from sperm whales detected by the system. Results transmitted to a ground station will be used to extrapolate the point where the whales should emerge. A high sensitivity and specificity detector is...

The WhaleSafe project aim is to detect and track sperm whale to prevent collisions with boats and ships by issuing warning messages in real time to the involved actors. Two buoys with four hydrophones onboard will be installed in Savona area and the collected data will be used to extrapolate the point where the whale should emerge. It is...

The ARION main objective is the creation of a virtual corridor for monitoring and surveillance of transient and resident bottlenose dolphins ({Tursiops truncatus). We deployed in the Portofino MPA two detection units, based on a particular type of marine buoy (elastic beacon) each equipped with four hydrophones and an acquisition system which...
