Nature of problem:The level density useful for nuclear reaction cross section calculations is calculated using a combined method [1]. At high excitation energy, the level density is computed using a quantum-statistical model [2]. At low excitation energy, the level density is calculated from the quasi- particle spectrum computed using the superfluid model. | ||

Solution method: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. | ||

Restrictions:Maximum number of quasiparticle to take into account for the quasi- particle spectrum calculations: three for odd system and four for even system. | ||

Running time: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. | ||
