Summary
Gamma-ray branching ratios have been carefully measured in16N, bombarding NH4NO3 targets enriched in15N with deuterons, using high-resolution gamma-spectrometers. The following results were obtained:I 276keV/I 396keV=2.76±0.06,I 100keV/I 276keV≤2·10−3 andI 176keV/I 296keV≤1·10−2. In the light of these branching ratios the muon partial capture rates to the16N excited bound states are reconsidered and briefly discussed.
Riassunto
Si sono accuratamente misurati i rapporti di suddivisione dei raggi γ in16N, bombardando con deutoni bersagli di NH4NO3 arrichiti di16N ed usando spettrometri γ di alta risoluzione. Si sono ottenuti i seguenti risultati:I 276keV/I 396keV=2.76±0.06,I 100keV/I 276keV≤2·10−3 eI 176keV/I 296keV≤1·10+2. In vista di questi rapporti di suddivisione si sono ristudiati e si discutono brevemente i rapporti di cattura parziali dei muoni negli stati legati eccitati del16N.
Резюме
Используя гамма-спектрометры с высокой разрешающей способностью, были аккуратно измерены отнощения ветвей гамма-излучения в16N, посредством бомбардировки мищеней NH4NO3, обогащенных15N, дейтронами. Получаются следующие результаты:I 276keV/I 396keV=2.76±0.06,I 100keV/I 276keV≤2·10−3 иI 176keV/I 296keV≤≤1·10−2. В свете этих отнощений ветвей занво рассматриваются и вкратце обсуждаются интенсивности парциальных захватов мюонов возбужденными связанными состояниями16N.
