alpha target in radius expansion

Submitted by southeast1012 on Tue, 06/02/2020 - 08:27

Hello everyone, I want to obtain a densest sample with equal sized spheres. I am using radius expansion method,and there is a factor named alpha target,referring to the packing density after expansion(I guess),and I want to know the maximum value of this factor that can be used,thanks.
Best regards.
