Nature of problem:
Program MIXING computes M1 reduced transition probabilities between pure Nilsson single particle states and also between states mixed by Coriolis and/or deltaN=2 interactions.
M1 reduced transition probabilities are calculated using the formulae given by Nilsson. The computation of the transition matrix elements is performed by the subroutine GM1. When the states are not pure, the program computes the transition probability taking into account the admixtures in the wavefunction. The resulting value given in units of e**2 X cm squared) is printed.
Mixed states with two or more components having the same values of the quantum numbers N and Omega are not allowed. Allowable maximum spin is 21/2. For higher values further factorials must be added to the data in the function CLESBSH. The program permits up to 20 admixtures in the wavefunction of each state and 8 Nilsson coefficients al Lambda for each orbital.
An option is provided to normalize the input Nilsson coefficients when necessary. This is performed by the subroutine NORMAL. The quantum numbers l and Lambda corresponding to each coefficient are calculated and printed.
