Abstract
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 ≤ Z ≤ 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
= 168–180) than from the parents in the lighter mass number (A = 156–166).
