image: In hypernuclear experiments, scientists are looking at those instances in which an electron strikes a proton with enough energy to transform it into two new particles: a kaon and a lambda hyperon. The original electron and the new kaon fly out of the nucleus, leaving the lambda hyperon behind. In this way, physicists have added an impurity to the nucleus -- a lambda hyperon -- that they can use to study the nucleus' structure. view more
