Nature of problem:
This program provides the theoretical values for the energy levels and ratios calculated with the AROVMI model in terms of the parameters gamma and rho.

Solution method:
A combination of graphical and numerical procedures is used to find the actual values of the model parameters. The Bessel formula is applied to interpolate energy levels predicted by the Davydov-Filippov model. The Newton-Raphson method is employed to find the root of a cubic equation.

Restrictions:
This program can be used for nuclei having combinations of experimental energy ratios R(14) and R(22) which fall within the bounds depicted in fig. 1a and b in the long write-up. Computations are performed with the energy levels of the ground-state rotational band from I=2 up to 20 (by steps of 2) and those of the anomalous (gamma) band for I=2 up to 10 (by steps of 1).
