For this, we have considered $^{206}$Hg $\\rightarrow$ $^{206}$Tl, $^{208}$Hg $\\rightarrow$ $^{208}$Tl, $^{206}$Tl $\\rightarrow$ $^{206}$Pb and $^{208}$Tl $\\rightarrow$ $^{208}$Pb transitions. We have performed shell model calculations using KHH7B interaction in valence shell 58-114 for protons and 100-164 for neutrons by considering ${\\it 1p-1h}$ excitations for both protons and neutrons simultaneously for daughter nuclei.
