Hydrogen Plasma At \(T_c\)

From the post "High Temperature Requires Thick Skin, Very Thick Skin",

\(T^{ 2 }_{ c }=\cfrac { (m_{ e }+m_{ p })^{ 2 } }{ m_{ e }m_{ p } } \cfrac { q^{ 2 } }{ \varepsilon _{ o } } { \tau _{ o } }\)

If we were to use

\(\tau_o\) = 6.486e13

For one hydrogen atom,

\(T_c\) = (( 9.10938e-31+1.67262e-27)^2/( 9.10938e-31*1.67262e-27)*(1.602176565e-19)^2/8.8541878176e-12*6.486e13)^(1/2)=1.859e-5 J.

\(T_c\approx\) 1.160e14 eV

This is the temperature that hydrogen form plasma readily, where  \(r_e=0\)  is a valid solution to the quadratic equation for  \(r_e\).  This value is still high.

No comments,  \(\tau_o\)  is still the new kid in town.
