Things I work on
Hi @JASory, I have been doing some research to find a package that could meet our needs on terrapower/armi#460 as a general nuclide library that can be imported across different languages, mainly Python at this time. I am learning Rust and came across this package and thought that it might be nice to collaborate!
After looking through your codebase, I am curious if we could work on the following functionalities:
I'd love to set up some discussions if you are interested and see if there is a way that we could develop requirements, documentation, and further testing! Please let me know 🙂
Implement partial decay, and Bateman's equation to accurately model the probability of the individual atom's identity.
Bh-276 and Bh-277 are recorded as Alpha decay; however the daughters are not recorded to exist.
During auditing, the following errors were found in the decaychain lookuptable, compromising a total of 119 errors out of 3585. Most errors are incorrect ratios due to parsing or unsupported decay modes.

It'd be great if the hard dependency on x86_64 was removed, and a cross-platform alternative is used instead, to allow the library to be used in other architectures
It's used in these two instances:
Replace the Bethe-Weizacker mass model with one that meets or exceeds the accuracy of the DZ10 model.
I'd like to expand the available functionality in this library by an Element
class that averages over isotopes so that I can use this library for chemical molecules, where atoms are most commonly represented as 'averages' over their isotopes.
This library already stores a lot of chemically relevant properties, such as electron affinity, ionization energies, electronegativities, etc. which are dependent on the atomic number only. I am aware I could write my own abstraction layer over the available data, but I would prefer to expand the scope of this library a little, so that the data is centralized and accessible for others.
Are you open to receiving a PR adding an Element
class implementing some or all of Atom
?
Element
can implement the full interface of Atom
. I've noticed that some functions, e.g. Nuclide::ionization_energies
will return f64::NAN
instead of None
for unavailable data. Is that intentional? Is that an escape hatch I could use?Element
interface?Atom
implement mass_deficit
/_kg
/_j
,_ev
and similar for binding energy, electron affinity, ionization energies, etc. could be made less redundant, e.g. with the crate uom
, which would also remove conversion constants from this library. I think this could be nice to have, but would probably be a different PR.A declarative, efficient, and flexible JavaScript library for building user interfaces.
