38K-isomeric state formation by (γ, n) reaction

  • Published:
Il Nuovo Cimento (1955-1965)

Summary

The article concerns measurements of photoneutron cross-sections for the ground and isomeric states formation of38K. FollowingHuizenga andVandenbosch, a comparison of the experimental branching ratio obtained was done with statistical theory. It was found that σ=2 for the distribution parameter of the density level formula fits better the experimental results. A tentative to observe a γ-decay of the isomeric to the ground state of38K was done.

Riassunto

L’articolo riguarda le misure delle sezioni d’urto dei fotoneutroni per la formazione degli stati fondamentale ed isomerico del38K. SeguendoHuizenga eVandenbosch, si è fatto un confronto fra i rapporti di branching sperimentali ottenuti e la teoria statistica. Si è trovato che il valore σ=2 per il parametro di distribuzione della formula della densità dei livelli approssima meglio i risultati sperimentali. Si è fatto un tentativo di osservare un decadimento γ dallo stato isomerico allo stato fondamentale del38K.
