Geo-neutrino studies are based on theoretical estimates of geo-neutrino spectra. We propose a method for a direct measurement of the energy distribution of antineutrinos from decays of long-lived radioactive isotopes. We present preliminary results for the geo-neutrinos from {sup 214}Bi decay, a process that accounts for about one-half of the total geo-neutrino signal. The feeding probability of the lowest state of {sup 214}Bi--the most important for geo-neutrino signal--is found to be p{sub 0…

Simulated Neutrino Signals of Low and Intermediate Energy Neutrinos on Cd Detectors
Neutrino-nucleus reactions cross sections, obtained for neutrino energies in the range $\varepsilon_{\nu}\leq 100-120$ MeV (low- and intermediate-energy range), which refer to promising neutrino
Convoluted -Signals on 114Cd Isotope from Astrophysical and Laboratory Neutrino Sources
At first, we evaluate scattering cross sections of low, and intermediate-energy neutrinos scattered off the 114 Cd isotope, the most abundant Cd isotope present also in the COBRA detector (CdTe and

Expected geoneutrino signal at JUNO
Constraints on the Earth’s composition and on its radiogenic energy budget come from the detection of geoneutrinos. The Kamioka Liquid scintillator Antineutrino Detector (KamLAND) and Borexino
Topical problems in low-energy neutrino physics
New data on solar-neutrino flux measurements are presented, and their compatibility with the Mikheev-Smirnov-Wolfenstein oscillation model is discussed. A review is given to topical problems in
Geoneutrinos and the radioactive power of the Earth
Chemical and physical Earth models agree little as to the radioactive power of the planet. Each predicts a range of radioactive powers, overlapping slightly with the other at about 24 TW, and
Nonaccelerator neutrino physics
The subject of these lectures is experimental nonaccelerator neutrino physics. We discuss experiments on solar and atmospheric neutrino flux measurements, as well as experiments devoted to recording

Comprehensive geoneutrino analysis with Borexino
This paper presents a comprehensive geoneutrino measurement using the Borexino detector, located at Laboratori Nazionali del Gran Sasso (LNGS) in Italy. The analysis is the result of 3262.74 days of
Lifetime measurements of 214Po and 212Po with the CTF liquid scintillator detector at LNGS
We have studied the α-decays of 214Po into 210Pb and of 212Po into 208Pb tagged by the coincidence with the preceding β-decays from 214Bi and 212Bi, respectively. The 222Rn, 232Th, and 220Rn sources


Borexino Collaboration
The Borexino detector measures solar neutrino fluxes via neutrino-electron elastic scattering. Observed spectra are determined by the solar-νe survival probability Pee(E), and the chiral couplings of
How much uranium is in the Earth? Predictions for geoneutrinos at KamLAND
Geo-neutrino detection can determine the amount of long-lived radioactive elements within our planet, thus providing a direct test of the bulk silicate Earth (BSE) model and fixing the radiogenic
Antineutrinos from Earth: A reference model and its uncertainties
We predict geoneutrino fluxes in a reference model based on a detailed description of Earth's crust and mantle and using the best available information on the abundances of uranium, thorium, and
Angular distribution of neutron inverse beta decay, ν̄ e +p-->e + +n
The reaction νe+p→e++n is very important for low-energy (Eν≲60 MeV) antineutrino experiments. In this paper we calculate the positron angular distribution, which at low energies is slightly backward.
The Borexino nylon film and the third counting test facility
The Borexino solar neutrino detector should begin operations in late 2006. This scintillationbased detector will observe low-energy neutrinos, in real time, down to about 250 keV. The experiment
