摘要：

We calculate the event rates induced by a Cr-51 nu e source and by a Sr-90-Y-90 <(nu)over bar>(e) source in BOREXINO through elastic scattering on electrons, assuming a nonzero neutrino magnetic moment mu(nu). We consider a source activity of about 2 MCi and estimate the solar nu ("source-off") background for various oscillation scenarios. It is shown that values of mu(nu) as low as similar to 0.5 x 10(-10) mu(B) (similar to 0.2 x 10(-10) mu(B)) can be proved with the Cr-51 source (Sr-90 source) in about 100 days of data taking.
