( H longrightarrow H+e^{-} I E_{1}=13 cdot 36 mathrm{eV} ) ( mathrm{He} rightarrow mathrm{ne}^{+}+mathrm{e}^{-} quad mathrm{IE}-1=24.6 mathrm{eV} ) Whe have fo determine values of [ begin{array}{l} H e^{2}+t e^{-} rightarrow H_{R}+Delta H=a H e^{+}+e^{-} rightarrow k e quad A H=b end{array} ] changl The onerall evergy can be witten as : ( therefore ) Total energy grien [ begin{array}{l} =a^{0}+b^{0} =[-53 cdot 44+(-24 cdot 6)] e v =78 cdot 04 times V end{array} ]
