Forming helium atoms#

To form a helium atom, an alpha particle that contains two protons and two neutrons is fixed at one location, and two electrons are brought from far away, one at a time. The first electron is placed a distance \(d = {{ params.d }}\times 10^{ {{ params.p }} }\rm\ m\) from the alpha particle and held there while the second electron is brought a distance \(d = {{ params.d }}\times 10^{ {{ params.p }} }\rm\ m\) from the alpha particle on the other side from the first electron. The final configuration of the particles is shown in the figure.
