Raymond davis jr.’s neutrino detector contained approximately 1030 chlorine atoms. during his experiment, he found that one neutrino reacted with a chlorine atom to produce one argon atom each day.
how many days would he have to run the experiment for 1% of his tank to be filled with argon atoms?
convert your answer from a. into years.
compare this answer to the age of the universe, which is approximately 14 billion years (1.4 × 1010 y).
what does this tell you about how frequently neutrinos interact with matter?
