Why is it experimentally found difficult to detect neutrinos in this process ?
Advertisements
उत्तर
Neutrinos are difficult to detect experimentally in β-decay because they are uncharged particles with almost no mass. Also, as neutrinos interact very weakly with matter, therefore, they are very difficult to detect.
