A study of the excited states of164Dy by means of the164Dy(n, n′γ)164Dy reaction

Summary

The γ-radiation following the inelastic scattering of neutrons from164Dy was studied for incident neutron energies from 580 keV to 2200 keV. From the analysis of the measured γ-ray spectra a detailed decay scheme of the nucleus was constructed, in which 30 energy levels and 44 γ-decays up to 2053 keV were determined. Level spins and parities were deduced comparing the experimental γ-ray excitation functions with the theoretical predictions based on the statistical model of the compound nucleus.

Riassunto

Si presentano i risultati di uno studio della reazione164Dy(n, n′γ)164Dy per energie di neutroni incidenti comprese fra 580 keV e 2200 keV. Dall’analisi degli spettri γ si è potuto ricostruire un dettagliato schema di decadimento, determinando 30 livelli energetici e 44 raggi γ fino ad un’energia d’eccitazione di 2053 keV. Si sono dedotti gli spin e le parità dei livelli confrontando le funzioni d’eccitazione sperimentali dei raggi γ con le previsioni teoriche basate sulla teoria statistica del nucleo composto.

Реэюме

При знергиях падаюших нейтронов от 580 кзВ до 2200 кзВ исследуется реакция164Dy(n, n′ γ)164Dy. Иэ аналиэа иэмеренных спектров γ-лучей конструируется подробная схема распада ядра, в которой определены 30 знергетических уровней и 44 γ-распада вплоть до знергии 2053 кзВ. Выводятся спины уровней и четности путем сравнения зкспериментальных функций воэбуждения для γ-лучей с теоретическими предскаэаниями, основанными на статистической модели компаунд-ядра.
