Abstract

The perturbed angular distributions of gamma rays de-exciting the 2+ and 4+ states of182W, recoil-implanted into iron after Coulomb excitation have been measured. A satisfactory fit of the rotation patterns could be obtained under the assumption of a static magnetic interaction, in contradiction to a previous measurement. The internal magnetic field acting on recoiled182W has been determined to be −555±75 kGauss, in fairly good agreement with Mössbauer experiments. A value for the transient field which is in agreement with that for the nearby Pt nucleus and with theoretical calculations has been found.

Резюме

Авторами было измерено возмуЩенное угловое распределение γ—лучей, испускаемых при разрядке уровней 2+ и 4+ в182W, ядра отдачи которого были внедрены в железо после кулоновского возбуждения. В противоречии с предыдущими измерениями была наблюдена картина вращения, описываемая лишь в предположении стационарного магнитного поля. Было определено значение внутреннего магнитного поля, действующего на ядро отдачи182W. Значение поля хорошо согласуется с результатами экспериментов типа Мэссбауера. Кроме зтого сделана оценка величины переходного поля. Полученная величина находится в хорошем согласии со значением поля для соседнего ядра Pt и с результатами теоретических оценок.
