内部転換(英語:Internal conversion、ICとも略記)は放射性崩壊の形式の一種。 励起された原子核(励起核)が、原子核内にも存在確率を有するS軌道の電子と直接に相互作用して、S軌道電子にエネルギーを与えて原子外に放出する。
94.7% of beta decays lead to an excited state of the nucleus : 85.1% return to the ground state by emitting an energetic 661.57 keV gamma, while 9.6% returns to stability through internal conversion. Our program of precision measurements of internal conversion coefficients (ICC) continued with the completion of the 134 Cs m and 137 Ba cases, and the measurement of a new case, 139 La. This program was An “internal conversion coefficient spectrometer” utilizing Ge(Li) and Si(Li) detectors has been used to make precision measurements of relative gamma-ray intensities for transitions following the decay of 192 Ir and 207 Bi, relative internal conversion line intensities for some transitions from 192 Ir, and conversion coefficients for some transitions from the decays of 51 Cr, 137 Cs, and The comparison source in this case was Cs 137.
Internal Conversion. Laboratory Exercise in Nuclear Physics. Autumn 2005. This laboratory exercise deals with a method of measuring the multi-polarity ofa transition in an atomic nucleus. By measuring (indirectly)the relative intensity of conversion electrons to radiation, the multi-polarity will be deduced.
