Classical theory of collisions is formulated which also includes uncertainty principle. The theory is used for the calculation of transition probabilities in the collinear He-H2 collision, and the results are compared with quantum calculations. Very good agreement is found.Klasična teorija sudara formulirana je uz uvažavanje principa neodredenosti. Izračunali smo prijelazne vjerojatnosti za kolinearni sudar He-H2 i usporedili rezultate s kvantnim proračunima. Pronašli smo vrlo dobro slaganje
