Title: Perspectives for geoneutrinos after KamLAND results
(work in collaboration with G. Fiorentini, M. Lissia, B
Ricci and R. Vannucci)
We present predictions of geo-neutrino fluxes, for KamLAND and other
locations, obtained within a reference BSE model.
When considering more general models, in which the total Uranium and
masses in the Earth are kept as free parameters, we show that a proximity
argument provides a well defined connection between geo-neutrino flux and
radiogenic heat production.
We compare KamLAND results with theoretical predictions and then we
discuss the size and location of geo-neutrino detectors which are
needed for providing answers to the following questions:
- How much Uranium and Thorium are in the Earth?
- How are Uranium and Thorium distributed between Crust and Mantle?
- Is there a radiogenic source in/near the core?
