tkn-exec.cpp

Compile a simple program using TkN

tkn-exec.cpp provides a simple example program using TkN to print the ground state spin parity of the Carbon isotopic chain.

To compile this example, use :

g++ tkn-exec.cpp -o tkn-exec `tkn-config --cflags --linklibs`

Source code :

#include "tkmanager.h"
 
using namespace tkn;
using namespace std;
 
int main()
{
    cout << "**************************************************" << endl;
    cout << "* Ground state spin parity in C isotopic chain   *" << endl;
    cout << "**************************************************" << endl;
    cout<<endl;
 
    // loop on the z=6 nuclei
    for(const auto &nuc : gmanager->get_nuclei([](auto nuc) {return (nuc->get_z()==6);})) {
        // get ground state level and print its spin-parity
        auto lvls =nuc->get_level_scheme()->get_levels([](auto lvl) {return (lvl->get_energy()==0);});
        cout << setw(5) << left << nuc->get_symbol();
        if(!lvls.empty()) cout << lvls.at(0)->get_spin_parity()->get_jpi_str();
        cout << endl;
    }
 
    return EXIT_SUCCESS;
}
