Greetings ! I'd like to ask a few questions about half-life (not the PC game ) functions: 1. Are they of the same shape for all nuclear particle decay reactions currently known and observed ? 2. What is the function mathematicly (and it's relevant shape of course) ? 3. What are the physical parameters if they are known (I guess not though) ? 4. Can the shape of the function help find a solution to the cause of the nuclear decay (if there is such a thing at all) ? Thanks ! Live long and prosper.
