Abstract
For the first time, events of formation, emission, and mesonic decay o f light hyperfragments LAMBDA/3 H and LAMBDA/4 H in annihilation of st opped antiprotons on nuclear-photoemulsion nuclei C, N, O, and S have been detected. It is established that a lower bound on the probability of formation of the hyperfragments LAMBDA/3 H and LAMBDA/4 H per anti proton stopped in the photoemulsion is (6.1 +/- 3.5) . 10(-4). It is s hown that the most probable mechanism of creation of hyperfragments is charge exchange of the K- mesons formed in annihilation on the nucleo ns of the residual nucleus.
