Not knowing whether there was a problem (1) with the theory, (2) with the experiment, So for several decades, scientists "lived" with the solar neutrino problem, Rending them the most difficult particles in nature to detect. Such an error in experiment would not be surprisingīecause neutrinos are extremely weakly interacting particles Others felt that Ray Davis and his co-workers were not measuring all the neutrinos Many astrophysicists did not believe that the solar models were sufficiently accurateĪnd that they were predicting too large a solar output. However, the situation was not conclusive.
So the radiochemical experiment of Davis indicated that neutrinos are massive. It is a fundamental result that neutrino oscillations Into its original form only to undergo the transformation again and again. Such a process is called neutrino oscillationīecause eventually the transformed neutrino will change back Mutate into one of the two other known types of neutrinos: That are created in the energy-producing core of the Sun Thereby creating the solar neutrino problem. The experiment was continued for two decades and the theory of the Sun was improved,īut the deficit in the observed number of neutrinos persisted The number of electron-neutrinos detected was less than the figure That measured neutrinos from the Sun using a large container of cleaning fluidĪs a neutrino detector in the Homestake Mine in South Dakota. In 1968, Ray Davis and his colleagues published the initial results of an experiment The first indications arose about 30 years ago. The realization that neutrinos have mass is an example of the latter.
Indeed, many scientific breakthroughs transpire in this manner.īut a few occur gradually, taking years or even decades to unravel. Or perhaps, after a week of analyzing a year's worth of data, On a particular day, an experiment leads to a remarkable result, Neutrinos Have Mass for Sure M ost people are under the impression that scientific discoveries happen rather suddenly:
