Present status of the ICARUS experiment

The T600 ICARUS detector, with a mass of about 600 tons of liquid argon (LAr), is the largest LAr Time Projection Chamber (TPC) ever built. It has been successfully tested in Pavia/Italy in 2001. More than 29,000 cosmic rays events have been collected during about 100 days of continuous data taking. It was demonstrated that large mass scale LAr TPC technique is operational. The T600 ICARUS test run results are briefly reported in this paper

ICARUS T600 - A large Liquid Argon Time Projection Chamber

The Liquid Argon Time Projection Chamber (LAr TPC) is a detection technique very well suited for the investigation of rare signals, including neutrino interactions. The ICARUS T600 is the largest LAr TPC ever built. It has recorded events both, from the CERN to Gran Sasso (CNGS) muon neutrino beam and cosmic rays interactions. Several important results have been achieved thanks to the three-dimensional event imaging and very good detector resolutions both, calorimetric and spatial. Two of them, namely the observation of a free electron lifetime exceeding 15 ms, and the search of LSND related anomalies in the νe appearance from the νμ CNGS beam will be shortly summarized

Ideas in neutrino physics

The ideas in neutrino physics are both, exciting and instructive. In this paper, a subjective review of several fundamental ideas and discoveries in this subject will be presented. We will focus on experimental aspects, starting from the discovery of electron neutrino, about 20 years after neutrino “theoretical birth” by W. Pauli, and finishing with short status of current techniques used in large scale neutrino physics experiments

Perspectives for glueballs search at future GSI antiproton facility

The present status of glueballs search is shortly reviewed, with special emphasis on search in proton-antiproton annihilation. The lattice QCD predictions for glueball mass spectrum are presented. We discuss the main requirements for the detector for glueball searches with the planned High Energy Storage Ring (HESR) at GSI Darmstadt. The parameters of the HESR are also given

Physics with the ICARUS detector

The multipurpose ICARUS detector, with its large sensitive volume, high granularity, excellent tracking and particle identification capabilities, is an ideal device for searching for phenomena beyond the Standard Model. A vast physics program, including accelerator (CNGS neutrino beam), and non-accelerator (supernova, atmospheric, and nucleon decay) physics, planned for the ICARUS detector, is reviewed

Spectroscopic amplitudes for the two - nucleon transfer between excited states of 1 p - shell nuclei

Spectroscopic amplitudes are calculated for a transfer o f two nucleons in the (S ,T = 1,0) and (0,1) states between low-lying, normal parity states of lp-shell nuclei. Calculations are performed with the intermediate-coupling model wavefunctions of nuclei considered. The wavefunctions were generated using the interaction parameters of Cohen and Kurath. These spectroscopic amplitudes are necessary for a description of two-nucleon transfer in one of intermediate steps of the multi-step sequential transfer process. Sum rules for the calculated spectroscopic amplitudes are given

Gamma background measurements in the Gran Sasso National Laboratory

In situ gamma-ray measurements were taken at eight locations in the Gran Sasso National Laboratory (Italy). Count rates for gamma radiation within the energy range of 7–2,734 keV varied from 8 to 60 c s-1. The arithmetic mean was 49 c s-1 for measurements taken without a collimator. The average gamma flux inside the Lab was 0.25 c cm-2 s-1. The sedimentary rocks surrounding the Lab are characterized by low activity concentrations of uranium and thorium, equal to 1.7 and 1.4 Bq kg-1, respectively

Six-nucleon spectroscopic amplitudes for 1p - shell nuclei. Pt. 2 Calculations and applications

Spectroscopic amplitudes for separation of six-nucleon clusters in low-lying states corresponding to the (ls)4(lp)2 shell-model configuration were calculated for lp-shell nuclei. The calculations were performed with the aid of intermediate-coupling model wave functions. The selectivity in excitation of the states produced in six-nucleon cluster transfer reactions with lp-shell nuclei is discussed. Sum rules for six-nucleon pickup and stripping are given

Gamma background measurements in the Laboratoire Souterrain de Modane

In situ gamma-ray measurements were taken at six locations in the Modane Underground Laboratory. Count rates for gamma radiation within the energy range of 7–2734 keV varied from 15 to 108 cs-1. The arithmetic mean was 79 cs-1 for measurements taken without a collimator. The metamorphic rocks surrounding the Lab are characterized by low activity concentrations of uranium and thorium equal to 12 and 10 Bq kg-1, respectively

Penetration of realistic potential barrier of H-I fusion

The calculations of heavy-ion fusion cross sections in the above and sub-barrier regions are presented. A barrier penetration model with matrix method for the calculations of transmission coefficients through real one-dimensional barrier of nucleus-nucleus potential is used. The renormalization parameter Ns of Satchler-Love M3Y nuclear potential and critical radius Rei are the two parameters of the model. A very good description of the experimental fusion cross sections for fp-shell colliding ions was obtained for the full measured energy range. It was found that both parameters Ns and reduced critical radius r„ are very similar for all systems considered and are-energy independent
