摘要：

Temperature dependences of the order parameter and the phase transition lines are calculated for the broken symmetry phase transition for a system of even-J, all-J and odd-J quantum rotors. Effect of positive and negative crystal fields is calculated and shown that these fields may turned out to be an important factor previously omitted in theory, which is responsible for a gap between theory and experiment.
