Query: Cluster Decay Half-Lives of 5d Transition Metal Nuclei Using the Coulomb
  and Proximity Potential Model   We have applied the Coulomb and proximity potential model,CPPM to calculate
the half lives for various clusters decay of the selected even-even isotopes of
the chosen nuclei. These nuclei are Hf, W, Os, Pt, and Hg in the 5d transition
metal region in the periodic table with atomic number 72 greater or equal Z
less than or equal 80. Furthermore, the half-lives are calculated using the
universal formula for cluster decay. The calculated half-lives of alpha decay
for the chosen isotopes are in good agreement with the experimental data,
especially with the CPPM results. The alpha and cluster decays are more
probable from the parents in the heavier mass number A equal 168,180 than from
the parents in the lighter mass number A equal 156, 166.
