The potential power of interactionbetween a cell nucleus (at the origin) and an electron as a role of street r in between them.The potential power is zero as soon as the 2 particles are really far apart(r = ¥ ), and also equals minus infinitywhen r amounts to zero. Us shall take the energy for r = ¥as ours zero that energy. Every energy will it is in measured loved one to this value.When a secure atom is formed, the electron is attractive to the nucleus,ris less than infinity, and also the power will be negative. A negative valuefor the energy implies that energy must be gave to the mechanism if theelectron is to overcome the attractive pressure of the nucleus and escapefrom the atom. The electron has again "fallen into a potential well." However,the shape of the well is no much longer a straightforward square one as previously consideredfor one electron border to relocate on a line, but has the shape shown inFig.3-1. This form is a consequence of there gift a pressure actingon the electron and also hence a potential energy contribution i m sorry dependson the distance between the 2 particles. This is the nature that the problem.Now let united state see what quantum mechanics predicts because that the motion of the electronin such a situation.
