- Atmospheric neutrinos travel very long distances through earth matter. It is expected that the matter effects lead to significant changes in the neutrino survival and oscil- lation probabilities. Initial analysis of atmospheric neutrino data by the Super-Kamiokande collaboration is done using the vacuum oscillation hypothesis, which provided a good fit to the data. Existence of matter effects is well established for solar neutrino oscillations but not for atmospheric neutrino oscillations. In this work, we did a study to differentiate the effects of vacuum oscillations and matter modified oscilla- tions in the atmospheric neutrino data. We find that magne- tized iron detector, ICAL at INO, can make a 3 σ discrimi- nation between vacuum oscillations and matter oscillations in ten years, for both normal and inverted hierarchies.
