Question Superheavy nuclei

Hi Forum people, I have a question regarding your RadioactiveDecay and PhotoEvaporation files.

The thing is I am working on superheavy nuclei. They start with proton number z=102, i.e. just above what is included in your RadioactiveDecay3.3 and PhotoEvaporation2.1 libraries.

To explore different hypotheses regarding the decay of these nuclei (which are notoriously hard to study) I would like to use a data file and simulate different ways to decay. Thus, ideally I would like to make up a file for nucleus z10X.aXXX. This file should then be editable to simulate for example different alpha energies or the order and intensity of the subsequent gamma rays.

I tried to do so but ran into various problems.

1a) When I make up a file with a new name the program does not want to accept it. Do I need to have produced the file already before compiling? It seems like there's no problem to take a already existing file (like z55.a131) and modify the decay in RadioactiveDecay3.3 (furthermore I have changed z54.a131 to simulate the nucleus decaying into an excited state in the daughter nucleus thus emitting gamma rays). 1b) Is there any way to only recompile the RadioactiveDecay3.3 and PhotoEvaporation2.1 libraries or do I need to wait though the whole 2h compilation process when I want to add a new file?

2a) I've been trying to find out the format of the data files in order to understand what I am actually simulating. Are there any documentation of this? The PhotoEvaporation2.1 have 17 input columns for each gamma ray and the RadioactiveDecay3.3 have 4 columns and a number of rows for each nucleus. Some of the numbers in the files are easy to understand and some are not clear to me at all.

3b) Are you aware of if there are any (unofficial) data files around which includes the decay of the superheavy elements? It is always easier not to start from scratch!

I would be very happy for some help and advice in this matter! Thanks, Lisa
