The author is indebted to Prof. K. Niu for calling his attention to that paper. Niu pointed out that there is a possibility to interpret tracks numbered as 3, 4, 5 and 6 of star I as a decay product of the new X0, since the resultant direction of them does not point to tho production point according to tho projection of that star. The point was communicated to the authors, but Niu did not yet get any answer from them.
