The energy distribution of Λ0coming from K capture stars has been obtained measuring Λ0found by area scanning in two emulsion stacks. This distribution, compared to a theoretical one obtained with an optical model calculation, gives indication that the percentage of multi-nucleon captures in nuclear emulsions of the order of 30%. To the same conclusion we are led by the detailed study of 103 capture stars correlated to Λ0decay. From the study of the missing energy in K-capture stars we deduce that the probability for a π0of being absorbed in nuclear matter is very low. There is evidence that the probability for the emission of a Λ0is not strongly dependent on the atomic weight of the nucleus in which the K-was absorbed. The upper limit for the cryptofragment formation is 15%. A search for the formation of Y1*-in the reactionat rest in the emulsion nuclei gives no conclusive result due to the low statistics. |
