Utilities for working with nuclear mass tables.

The Nuclear Mass Table Toolkit provides utilities to work with nuclear mass tables. At the moment the following tables are supported:

  • AME2003: G. Audi, H. Wapstra, C. Thibault, Nucl. Phys. A 729 (2003) 337
  • AME2003all: Same as above but including interpolated("#") values
  • AME2012: G. Audi et al, Chinese Physics C. 36, No. 12(2012)
  • AME2012all: Same as above but including interpolated("#") values
  • AME1995: Audi, G., and A. H. Wapstra, Nuclear Physics A 595 (4) (1995): 409-480
  • AME1995all: Same as above but including interpolated("#") values
  • DUZU: J. Duflo, A.P. Zuker, Phys. Rev. C 52 (1995)
  • FRDM95: Moller, P. et al., At. Data and Nuc. Data Tables 59 (1995) 185
  • KTUY05: H. Koura, T.Tachibana, M. Uno, M. Yamada, Progr. Theor. Phys. 113 (2005) 305
  • ETFSI12: Y. Aboussir et al., At. Data Nucl. Data Tables 61 (1995) 127
  • MAJA88: Masson, P. J., and J. Jänecke, Atomic Data and Nuclear Data Tables 39.2 (1988): 273-280.
  • GK88: Jänecke, J., and P. J. Masson, Atomic Data and Nuclear Data Tables 39.2 (1988): 265-271.
  • HFB14: S. Goriely, M. Samyn, J.M. Pearson, Phys. Rev. C 75 064312 (2007)
  • HFB26: S. Goriely, N. Chamel, J.M. Pearson, Phys. Rev. C 88 024308 (2013)
  • WS32010: N. Wang, Z. Liang, M. Liu, X. Wu, Phys. Rev. C 82 044304 (2010)
  • WS32011: M. Liu, N. Wang, Y. Deng, X. Wu, Phys. Rev. C 84 014333 (2011)

Usage:

  • Print first 5 elements from Audi 2003:
>>> from masstable import Table
>>> Table('AME2003').head()
Z  N
0  1     8.07132
1  0     7.28897
   1    13.13570
   2    14.94980
   3    25.90150
  • Calculate the root mean squared error of Moller, et al. Atomic Data and Nuclear Data Tables, 59 (1995), 185-351.
>>> Table('FRDM95').rmse(relative_to='AME2003')
0.890859326191
  • Calculate 2 neutron separation energies for even-even nuclei:
>>> table = Table('AME2012').even_even.s2n
Z  N
2  2           NaN
   4      0.975454
   6      2.125034
   8     -1.417666
4  2           NaN
       ...
  • Select nuclei with Z,N > 28:
>>> condition = lambda Z,N: Z > 28 and N > 28
>>> table.select(condition)
30  30    28.016334
    32    23.136434
    34    20.978934
    36    19.037934
    38    17.250334
    40    15.700534
       ...
  • Plot binding energies per nucleon:
>>> t = Table('AME2012')
>>> (t.binding_energy/t.A).plot()
