A liquid Argon TPC (ICARUS-like) has the ability to detect neutrino bursts from type-II supernova collapses, via three processes: elastic scattering by electrons from all neutrino species, and νe charged current absorption on Ar with production of excited K and νe charged current absorption on Ar with production of excited Cl. In this paper we have used new calculations in the random phase approximation (RPA) for the absorption processes. The anti-neutrino reaction νe 40Ar absorption has been considered for the first time. For definiteness, we compute rates for the 3 kton ICARUS detector: 244 events are expected from a supernova at a distance of 10 kpc, without considering oscillation effects. The impact of oscillations in the neutrino rates will be discussed in a separate paper. We also discuss the ability to determine the direction of the supernova.
