[Polhe3] polhe3 emaillist created

[Zhiwen Zhao]

Hi, folks

I create a "polhe3" emaillist for the future polarized He3 target 
development.
If you got this email, that means your address has been added in the 
list and you don't have to do anything.

If you want to change your subscription email, please go to
https://mailman.jlab.org/mailman/listinfo/polhe3

Please let others who may be interested know the list.

cheers

Zhiwen
