Summary

94Zr energy levels up to ⋍4.3 MeV excitation energy are studied in the reaction94Zr(d, d′)94Zr*. Deuterons had a bombarding energy of 15.5 MeV. The emergent deuterons were analysed by a magnetic spectrograph and the detector was nuclear emulsion. The resolution in energy was about 11 keV. We used the distorted-wave analysis to determine thel transferred, the ß 2l and Jπ values for some94Zr excited states. Our results are compared with previous ones. 32 levels of excitation energy in94Zr were found which did not appear in previous94Zr(d, d′) reactions. 20 levels do not correspond to the adopted ones.

Riassunto

Si studiano i livelli di energia dello94Zr flno all’energia di eocitazione di circa 4.3 MeV nella reazione94Zr(d, d′)94Zr*. I deuteroni hanno un’energia di bombardamento di 15.5 MeV. I deuteroni emergenti sono stati analizzati mediante uno spettrografo magnetico e il rivelatore era ad emulsione nucleare. La risoluzione in energia era di circa 11 keV. Abbiamo usato l’analisi mediante onda distorta per determinare i valori dell’l trasferito, del ß 2l e del Jπ per alcuni stati eccitati dello94Zr. I nostri risultati sono stati paragonati ai precedents Sono stati trovati 32 livelli di energia di eccitazione in94Zr, i quali non erano presenti nelle prime reazioni dello94Zr(d, d′). 20 livelli non corrispondevano a quelli adottati.

Резюме

Исследуются уровни э нергии в94Zr при энергиях возбуждени я вплоть до - 4.3 МэВ в реакции94Zr(d, d′)94Zr*. Бомбардирующие дейт роны имеют энергию 15.5 МэВ. Вылетающие дейт роны анализируются с помощью магнитного спектрог рафа и детектора с ядерной эмульсией. Энергетич еское разрешение составля ет 11 кэВ. Мы про одим анали з искаженных волн, что бы определить передачу l, величины β 2l и Jπ для не которых возбужденны х состояний94Zr. Полученн ые результаты сравниваются с имеющ имися в литературе. Об наружены 32 уровня в94Zr, которые не приводили сь в реакции94Zr(d, d′). 20 уровн ей не соответствуют ранее установленным значе ниям.
