I found the following (for what it’s worth):(adsbygoogle = window.adsbygoogle || []).push({});

ln(mu/me) / (2pi-3/pi) = 1.000627

ln(mt/me) / (3pi-4/pi) = 1.00031

me = 0.51099892 MeV (+/-0.00000004)

mu = 105.658369 MeV (+/-0.000009)

mt = 1776.99000 MeV (+0.29 -0.26)

I've not seen it before. There's no theory behind it.

I was trying one, made a bug and stumbled on it.

Regards, Hans
