Determination of the branching fractions for K-meson absorptions at rest in carbon nuclei

Определение отнощений ветвей для поглошений K-мезона в покое на ядрах углерода

  • Published:
Il Nuovo Cimento A (1965-1970)

Summary

The branching ratios for the primary interactions of K-mesons at rest with carbon nuclei have been determined by means of a heavy-liquid bubble chamber filled with a mixture of hydrocarbons. The results are compared with those obtained in other absorbing media, and the question of the existence of a halo of neutrons at the surface of heavy nuclei is discussed in the light of these new results.

Riassunto

Si sono determinati i rapporti di diramazione per le reazioni primarie dei mesoni K in quiete con nuclei di carbonio per mezzo di una camera a bolle a liquido pesante riempita con una miscela di idrocarburi. Si confrontano i risultati con quelli ottenuti in altri mezzi assorbenti, e si discute la questione dell'esistenza di un alone di neutroni alla superficie dei nuclei pesanti alla luce di questi nuovi risultati.

Резюме

Определяются отношения ветвей для первичных взаимодействий K-мезонов в покое с ядрами углерода, используя тяжеложудкостную пузырьковую камеру, наполненную смесью углеводородов. Полученные результаты сравниваются с результатами, полученными в других пиглошаюших средах. В свете этих новых результатов обсуждается вопрос сушествования гало нейтронов на поверхности тяжелых ядер.
