Neutrino changes chlorine to argon

  1. Jan 27, 2015 #1
    A neutrino converts a chlorine-37 atom into one of argon-37
    A neutrino is also able to react with an atom of gallium-71, converting it into an atom of germanium-71

    It looks to me as if the neutrino was changing into a proton in both cases as argon has 1 more proton than chlorine and likewise with germanium and gallium.
    But this really doesn't seem right.

    Can somebody explain?

    It converts a neutron into a proton plus an electron. The number of protons increases by 1, the number of neutrons decreases by 1, their sum (37 and 71 respectively) does not change.

    A slightly embarrassed thanks. Haven't touched physics for a while.
