The calculations show that the total cross section is about a few $μ$b for the first processes and a few mb for the second reactions at energy close to the threshold. Then it decreases with increasing energy according to the true Regge asymptotics.6 pages, 3 figures; published in the Proceedings of the International Conference ``I. Ya.
