The name of the atomic species.

f_tot = 2

Total angular momentum f_tot of the Rydberg state.

parity = 1

Parity (-1 or +1) of the Rydberg state, i.e. (-1)^(l_c + l_r) of its channels.

nu_range = (5.7, inf)

Range of effective principal quantum numbers nu for which the MQDT model is valid.

List of outer channels in the MQDT model.

Elements of the symmetric K-matrix in the outer channel frame.

Each entry is a tuple (i, j, coefficients) with the indices i <= j of the involved outer channels and coefficients the list of expansion coefficients [K⁽⁰⁾, K⁽¹⁾, …] of the polynomial in the energy variable epsilon (a constant element is a single element list). Only the upper triangle needs to be given, the lower triangle follows from the symmetry of the K-matrix. Elements not given are zero.
