Detailed Description

Represents a core potential.

General Core Potential is able to write down as following form: $U(r) = \sum_k A_k r^(n_k-2) exp(-alpha_k r^2) \sum_m |Y_lm \rangle \langle Y_lm|$ CorePotential holds these parameters (l,n,A,alpha)

Note: CorePotential::eval() currently ignores ‘l’. (It means ‘ $\sum_m |Y_lm \rangle \langle Y_lm|$ ’ is always ‘1’.)
