TkN: Version 2.0

Data sources and content

• Adding properties from the IAEA-NDS API, namely:
  • mass excess
  • charge radius
  • magnetic dipole
  • electric quadrupole
  • year of isotope discovery.
• Removing properties:
  • binding energy minus Liquid Drop model fit
  • thermal neutron capture cross section
  • thermal neutron fission cross section
• All properties deduced from the mass excess are now directly recalculated in TkN.

tknucleus

• Adding the methods:
  • get_radius(): returns the nuclear radius in fm
  • get_magnetic_dipole(): returns the magnetic dipole moment in μN
  • get_electric_quadrupole(): returns the electric quadrupole in barn
  • get_lifetime_str(): returns the lifetime in string using the best adapted time unit
  • get_discovery_year(): returns the isotope year of discovery
  • is_known(): returns a boolean to true if the nucleus is known

tklevel

• adding levels based on an unkown bandhead energy (E_lev = X + E_rel) and related gamma transitions.
• adding methods:
  • to test if the level is known with an offset: is_energy_offset()
  • to retrieve the offset value: get_offset_bandhead()
  • to get the energy of the ralive energy (adding parameter _with_offset in get_energy())
• correction of a bug on the spin values

tklevel_scheme

• correction of a bug on some of the adopted datasets that were skipped

tkdatabase

• correction of a bug in the reading of the SQlite database
• correction of an error in the float precision of the extracted values from the database

tkunits

• correction of a bug in the year/seconds time conversion

tkmeasure

• add addition, soustraction, and multiplier operators between tkmeasure objects

tkn-root

• correction of a bug. No more need to include tkmanager.h to access tkn classes
