Abstract

In doing so, the team could estimate how often the electron bounced off a recoiling nucleon from a proton-proton or proton-neutron interaction. Rather than the 3 per cent measured in earlier experiments, proton-proton interactions were involved 20 per cent of the time. By watching how the proton and electron recoiled, they were able to measure how much the proton was stretched by the interaction. Features DEEP in the heart of every atom lurk protons, tiny particles from which the chemical elements were forged, first in the searing heat of the big bang and then in the nuclear furnaces of stars.
