Lifetime of a decaying nucleus changes with temperature?

In summary, the conversation discusses whether the mean lifetime of a decaying nucleus changes with temperature. While it is generally believed that the mean lifetime remains constant, there are some anomalous data that suggest otherwise. A link provided by Simon offers additional insight on the topic.

hello,

does the mean lifetime of a decaying nucleus changes with temperature?
I generally think that mean lifetime of a given nucleus doesn't change with temperature.

thanks for your valuable input.

A quick google and 2nd year undergrad experience tend towards "no, not in theory" , but it seems that there are some interesting anomalous data to be found.

hello,
thank you very much.
I actually thought that mean lifetime of a given nucleus is always a constant..doesn't depend on temperature (i did not find any notes on internet)..I am just studying the relax. phenon. compared to life time, stuffs..
You reply+link is extremely helpful.
 

Related to Lifetime of a decaying nucleus changes with temperature?

1. How does temperature affect the lifetime of a decaying nucleus?

The lifetime of a decaying nucleus is inversely proportional to temperature. This means that as temperature increases, the lifetime decreases.

2. Why does the lifetime of a decaying nucleus change with temperature?

The lifetime of a decaying nucleus is affected by temperature because at higher temperatures, there is more thermal energy available for the particles to overcome the energy barrier and decay, resulting in a shorter lifetime.

3. Is there a relationship between temperature and the rate of nuclear decay?

Yes, there is a relationship between temperature and the rate of nuclear decay. As temperature increases, the rate of nuclear decay also increases.

4. Can temperature control the rate of nuclear decay?

Yes, temperature can control the rate of nuclear decay. By adjusting the temperature, we can control the amount of thermal energy available for particles to overcome the energy barrier and decay.

5. How does the change in lifetime of a decaying nucleus with temperature impact radioactive dating techniques?

The change in lifetime of a decaying nucleus with temperature can impact radioactive dating techniques because it affects the rate of nuclear decay, which is used to determine the age of a sample. Any changes in the lifetime of the decaying nucleus due to temperature must be taken into account for accurate dating results.
