Nature of problem:
The level density useful for nuclear reaction cross section calculations is calculated using a combined method . At high excitation energy, the level density is computed using a quantum-statistical model . At low excitation energy, the level density is calculated from the quasi- particle spectrum computed using the superfluid model.
The energy range to compute level density is divided in two intervals: first, from zero to some value of excitation energy, where level density is calculated using a combinatorial method and the second one from the matching energy to final excitation energy, where a quantum-statistical method is used to compute level density.
Maximum number of quasiparticle to take into account for the quasi- particle spectrum calculations: three for odd system and four for even system.
Depends on the choice for calculation. To compute only quasiparticle spectrum the running time is approximately 43 seconds and to calculate statistical level density the running time is approximately 7 seconds. For test, in which both choices are computed the running time is 50 seconds.
