Description

A method is proposed to select core and cluster in a binary description of nuclei. The choice is based on the mismatch between measured binding energies and the underlying trend supplied by the liquid drop model. A key point is that the charge to mass ratios of parent, core and cluster should be as nearly equal as possible. In binary models, the transition quadrupole moments of superdeformed (SD) bands depend strongly on the charge and mass splits. Calculations of transition quadrupole moments are compared with the measured values for the 41 SD bands in 21 even-even nuclei. A good level of agreement is obtained

Abstract (Russian)

Предлагается метод выбора кора и кластера в бинарном описании ядер. Этот выбор основан на рассогласовании между измеренными значениями энергий связи и расчетами по капельной модели. Ключевой момент заключается в том, что отношения заряда к массе кора, кластера и родительского ядра должны быть равны. В бинарных моделях переходный квадрупольный момент сверхдеформированных (СД) полос сильно зависит от зарядового и массового расщеплений. Рассчитанные моменты сравниваются с измеренными для 41 СД полосы в 21 четно-четном ядре. Получено хорошее совпадение
