Abstract

The possibility of detecting the [FORMULA] burst from the collapse of a neutron star into a black hole is discussed for an existing SN neutrino detector.

The expected signal has been evaluated on the basis of the model predictions on the [FORMULA] emission and compared with the detector background. The experimental conditions are discussed in order to maximize the signal to noise ratio.

A fraction up to [FORMULA] (depending on the [FORMULA] energy spectrum) of the stars of our Galaxy, distributed through distances which extent up to the Galactic Center, could be observed by a [FORMULA] liquid scintillator detector such as the Large Volume Detector at Gran Sasso.

Key words: black hole physics – stars: neutron
