One Of A Kind

From the post "Small Negative, Big Positive" dated 24 Dec 2014,

$\cfrac{a_{\psi\,\pi}}{a_{\psi\,ne}}\lt 1.5$

at the limit,

$\cfrac{a_{\psi\,\pi}}{a_{\psi\,ne}}=1.5$

In the case of temperature particle, $a_{\psi\,\pi}=273.43\,nm$

${a_{\psi\,ne}}=\cfrac{273.43}{1.5}=182.29\,nm$

This particle is neutral.

$\left.\cfrac { dq }{ dx }\right|_{ a_{ \psi \,ne} }=\left.3 \cfrac { \partial V\,  }{ \partial \, x } \right|_{x=a_{\psi\,\pi}}$

when two of its kind interact.  But this particle is attracted by, $a_{ \psi \,c }$

$\left.\cfrac { dq }{ dx }\right|_{ a_{ \psi \,c } }=\left[3 \cfrac { \partial V\,  }{ \partial \, x } -1.49824\cfrac { \partial \, T }{ \partial \, x } \right]_{x=a_{\psi\,\pi}}$

and repelled by, $a_{ \psi \,\pi }$

$\left.\cfrac { dq }{ dx }\right|_{ a_{ \psi \,\pi } }=\left[3 \cfrac { \partial V\,  }{ \partial \, x } +\cfrac { \partial \, T }{ \partial \, x } \right]_{x=a_{\psi\,\pi}}$
