# Initial values of parameters for variable moment of inertia models

## Description

Title of program: INVAP Catalogue Id: ABQN_v1_0 Nature of problem The long write-up summarizes the procedure for determining the initial values of parameters for the fitting of rotational spectra in even-even nuclei. The functional form of the fitting is: E_I=C_2(J_i-J_0)^2 + C_3(J_I- J_i-J_0)**3 + C4(Ji-J0)^4 + ... with the condition delta E_I/delta J_I = 0, where E_I and J_I are the excitation energy and moment of inertia at a certain angular momentum I, respectively, and C_i and J_0 are the parameters of interest. While the determination of these parameters can be done fo ...
