An electron is in the ground state of the tritium atom for which the nucleus consists of one proton and two neutrons. Suppose the nucleus instantaneously changes into He”, consisting of two protons and a neutron due to a nuclear reaction. What is the probability that the electron is found in the ground state of the Heion? The is sometimes called the “sudden approximation”
