Lifetime of a decaying nucleus changes with temperature?

[Rajini]

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..
