Positronium is just like a H-atom with the proton replaced by the positively charged anti-particle of the electron (called the positron which is as massive as the electron). What would be the ground state energy of positronium ?

To find the ground state energy of positronium, we can follow these steps: ### Step 1: Understand the System Positronium is similar to a hydrogen atom, but instead of a proton, it has a positron (the antiparticle of the electron). Both the electron and positron have the same mass, denoted as \( m_e \). ### Step 2: Use the Formula for Energy Levels The energy levels of a hydrogen-like atom can be expressed as: \[ ...
