Bohr Hamiltonian with hyperbolic Pöschl-Teller potential for triaxial nuclei
Tóm tắt
The Bohr Hamiltonian for the triaxial nuclei with Pöschl-Teller potential for the
$\beta$
-part and a harmonic oscillator around
$\gamma = \frac{\pi}{6}$
for the
$\gamma$
-part is solved. An approximate separation of the variables occurs when the potential has the form
$v(\beta,\gamma)=u(\beta)+v(\gamma)$
. The
$\beta$
-part has been solved using the Nikiforov-Uvarov method. The total wave function has been derived and an expression for the total energy is represented. The electric quadrupole transition rates are evaluated. The spectra and B(E2) s are compared to the experimental data.
