Il Nuovo Cimento A (1965-1970)

Summary

The excitation function of the58Fe(p, γ)59Co reaction was measured in the analogue regionE p=(2150 ÷ 2270) keV. Gamma-ray spectra were measured at four resonances; excitation energies and branchings of the resonance levels and several bound states were extracted. A decay scheme involving 36 excited states is proposed for59Co. AQ value of (7363.2 ± 1.4) keV was obtained for the reaction58Fe(p, γ)59Co. Total and partial radiation widths and inelastic widths were measured for eight components of the fragmented analogue of the59Fe ground state. The strength of the analogue to antianalogue transition was found to be 0.07 W.u. Correlations between different channels were investigated.

Riassunto

Si è misurata la funzione di eccitazione della reazione58Fe(p, γ)59Co nella zona dell’analogo dello stato fondamentale del59Fe ad energia dei protoni incidenti compresa tra 2150 e 2270 keV. Dalla misura degli spettri γ di decadimento di 4 risonanze sono stati ricavati le energie di eccitazione ed i rapporti di diramazione degli stati risonanti e di numerosi stati a bassa energia di eccitazione. Si propone uno schema di decadimento comprendente 36 stati eccitati. Si è ottenuto un valore di (7363.2 ± 1.4) keV per ilQ della reazione. Sono state misurate le larghezze di decadimento γ totali e parziali e di diffusione anelastica per 8 componenti dell’analogo frammentato. L’intensità della transizione analogo-antianalogo è risultata 0.07 W.u. Si sono esaminate le correlazioni fra vari canali di decadimento.

Реэюме

Проводились иэмерения функции воэбуждения реакции58Fe(p, γ)59Co в областиE p=(2150 ÷ 2270)кзВ. Иэмерялись спектры гамма-лучей для четырех реэонансов. Определялись знергия воэбуждения, ветвления реэонансных уровней и некоторые свяэанные состояния. Для59Co предлагается схема распада, включаюшая 36 воэбужденных состояний. Для реакции58Fe(p, γ)59Co получаетсяQ-величина, равная (7363.2±1.4)кзВ. Иэмерялись полные и парциальные щирины и неупругие щирины для восьми компонент фрагментированного аналога основного состояния59Fe. Была получена интенсивность перехода аналога в анти-аналог, которая составляет 0.07 W.u. Исследуются корреляции между раэличными каналами.
