| Popis: | A theoretical study of nuclear level density of Thorium nuclei that exist on and off the beta-stability line is carried out using Talys 1.6. The level density parameter a and spin cut-off factor [Formula: see text] for Thorium isotopes [Formula: see text]Th are estimated. The values of both these parameters decrease towards the neutron drip line and the proton drip line. Cross-sections for [Formula: see text] and [Formula: see text] reactions for Thorium isotopes are also calculated. The estimated and experimental values of cross-sections for [Formula: see text]Th are comparable. These evaluated data are useful in understanding the mechanism of nuclear reactions taking place under extreme conditions including those in nucleosynthesis. |
