NAME

sierk_bfis, sierk_egs, sierk_mom, sierk_lmax - Return Sierk barrier height, ground state energy, principal-axis moments of inertia and maximum angular momentum

SYNOPSIS

#include <sierk.h>

double sierk_bfis(int Z, int A, double L);

double sierk_egs(int Z, int A, double L);

void sierk_mom(int Z, int A, double L,
double *
Imin, double *Imid, double *Imax);

double sierk_lmax(int Z, int A);

double sierk_mom0(int Z, int A);

double sierk_rot0(int Z, int A, double L);

Link with -lnuclib.

DESCRIPTION

The sierk_bfis() function returns the barrier height in units of MeV, calculated by A. J. Sierk using Yukawa-plus-exponential double folded nuclear energy, exact Couloub diffuseness corrections, and diffuse-matter moments of inertia. Likewise, sierk_egs() returns the ground-state energy in units of MeV, sierk_mom() returns via pointers the three principal-axis moments of inertia and sierk_lmax() returns the angular momentum in units of h-bar (Planck’s constant divided by 2*pi) at which the fission barrier disappears. The sierk_rot0() function returns the rotational energy of the rotating equilibrium ground state in units of MeV.

Z A

Atomic and mass number of the nucleus.

L

Angular momentum of nucleus in units of h-bar.

Imin Imid Imax

Principal-axis moments of inertia in units of the moment of inertia of a rigidly rotating, sharp-surfaced sphere, 2/5 mr^2, where r = 1.16*A^(1/3) fm, and m is 931.5016*A - 0.511004*Z MeV/c^2, which is a value returned by the function sierk_mom0().

RETURN VALUE

The functions sierk_bfis(), sierk_egs(), sierk_lmax(), sierk_mom0() and sierk_rot0() return the values described. sierk_mom() returns the values described via pointers.
