Determination of 207Bi activity and detection efficiencies by using the method of X-gamma coincidences

请选择邀稿期刊:
摘要: We present an enhancement of the matrix method of X-gamma coincidences by simplifying the way of obtaining counting rate equations of the commonly used detection pathways. That empowers getting an algebraically non-truncated, closed-form, counting rate equations for the complex schemes of radioactive decays. We applied the method to the radioisotope of bismuth, 207Bi. The daughter nuclei of this radioisotope have a metastable state that induces the splitting of the true coincidence pathways which have to be addressed in the counting rate equations.
