Positronium in a Liquid Phase: Formation, Bubble State and Chemical Reactions

Figure 14

Dependences of the optimal parameters 𝑎 and 𝑏 versus 𝑅, the bubble radius. They enter the 𝑒⁺𝑒⁻ wave function and yield the minimum of the total energy ⟨𝐻⟩. The relative contact density 𝜂_𝑐 and different energy contributions to ⟨𝐻⟩ (at optimal 𝑎 and 𝑏) are shown as well. It was assumed that 𝜀=2.
