✦ Synopsis

We present the latest results on the study of atmospheric neutrino oscillations with the MACRO detector at Gran Sasso. Two sub-samples of events have been analysed, both in terms of absolute flux and zenith angle distribution:

high energy events (with (&) 21 50 GeV) and 1 ow energy events (with (&) N 4 GeV). The high energy sample has been used also to check the V~ t) v sterile oscillation hypothesis and to estimate neutrino energies using Multiple Coulomb Scattering (MCS) informations. All these analyses are mutually consistent and strongly favour the vfi f) v, oscillation hypothesis with maximal mixing and Am2 = 2.5 10m3eV2.
