This FORTRAN code is designed to calculate exact total and particle-hole
state densities for a given single particle level scheme. The state
density is obtained under the independent particle assumption.
Therefore no residual interaction can be considered in this approach.
The obtained total and/or particle-hole level densities can be used in
preequlibrium and equilibrium nuclear reaction models calculations or as
input for refined nuclear level density calculations, where residual
interactions can be accounted for. Both odd and even systems can be
treated.
Method of solution:
A method which is mathematically exact is used; its key element being
a recursion relation for the calculation of the coefficients of a finite
order partition function as proposed by Williams [1].
Restrictions:
The calculation time depends strongly on the highest excitation energy
requested.
Typical running time:
Depends on the number of excited quasiparticles requested for the
particle-hole state density calculation, on the energy accuracy of the
single-particle level scheme and on the number of particles and number
of single-particle levels. In the example where total and particle-hole
state densities have been calculated up to 15 MeV for a 60Ni nucleus,
the running time was 2 min using Microsoft Power Station 4.0 optimizing
compiler in a Pentium class microcomputer running at 800 MHz.
