In summary, we are discussing the internal conversion coefficient for the de-excitation of 123I through electron capture to an excited state of 123Te, which has an energy of 159keV. It is noted that 97.7% of disintegrations result in this decay and 82.9% of these decays are followed by the emission of gamma rays with an energy of 159keV. The internal conversion coefficient is calculated by dividing the percentage of decays not resulting in gamma emission (17.1%) by the percentage of decays resulting in gamma emission (82.9%) and dividing that by the fluorescence yield. This calculation is only applicable to the decay of tellurium, not iodine.

"In 97.7% of disintegrations 123I decays by electron capture to an excited state of 123Te, which has an energy of 159keV. Gamma rays of energy 159keV are emitted following 82.9% of decays. What's the internal conversion coefficient for this de-excitation?"


I know that a=Ne/Ny(gamma), but I'm kind of confused here about the percentage of the decays of the e- capture & gamma emission. Is it 97.7%/17.1%=5.713?

Any help would be greatly appreciated!

gamma emmission 82.9%
rest x-ray emmission + flrorascence yeild

so icc = (17.1/82.9)/ (florascence yeild)

the 97% is just the percentage of time iodine decays through electron capture, we are interested only in tellurium decay!.

This is for now my understanding
 

Related to Internal Conversion Coefficient/Decay % HELP

1. What is an internal conversion coefficient?

An internal conversion coefficient (ICC) is a measure of the efficiency with which an excited atom or nucleus converts its energy into an internal conversion electron. It is expressed as a decimal fraction or percentage and is specific to a particular decay process.

2. How is the internal conversion coefficient calculated?

The internal conversion coefficient is calculated by dividing the number of internal conversion electrons emitted by the total number of decay events. This can be determined experimentally by measuring the intensities of the different types of radiation emitted during a decay process.

3. What is the relationship between internal conversion coefficient and decay percentage?

The internal conversion coefficient and decay percentage are two ways of expressing the same concept - the efficiency of a decay process. The internal conversion coefficient is a decimal fraction, while the decay percentage is a percentage, but they both represent the proportion of decay events that result in an internal conversion electron.

4. How does the internal conversion coefficient affect the decay rate?

The internal conversion coefficient has no direct effect on the decay rate. It is simply a measure of the efficiency of a decay process. The decay rate is determined by the decay constant, which is a characteristic of the specific atom or nucleus undergoing decay.

5. Why is the internal conversion coefficient important in nuclear physics?

The internal conversion coefficient is important in nuclear physics because it provides valuable information about the structure and decay properties of atoms and nuclei. It can also be used to study the nature of the interaction between electrons and the nucleus, and to determine the multipolarity of nuclear transitions.
