ABSTRACT
In
this paper, a method of defining the even-even deformed nuclei inertial
parameters is suggested. Calculations for isotopes 162-168Hf
and 164-176Yb are listed. The parameters of inertia of
rotational nuclei are also defined. Dependence of the parameters of inertia on
the nucleons number is shown.
Keywords:
Collective level; nuclear structure models and methods; properties of nuclei
ABSTRAK

kertas ini, dicadangkan satu kaedah untuk menakrifkan parameter inersia bagi
nukleus tercangga genap-genap. Penghitungan untuk isotop 162-168Hf
dan 164-176Yb disenaraikan. Parameter untuk inersia bagi
nukleus putaran juga ditakrifkan. Kebersandaran parameter inersia ke atas
nombor nukleon ditunjukkan.
