In Ref. ^{1}, estimated value of the overlap integral square $K(s\xaf,\omega )/A$, using (1), (2) and experimental results of the absorption of colloidal CdS QDs, synthesized by an aqueous synthesis in a gelatin matrix was investigated. For the hole transitions from the equidistant quantum levers: ($nh=0;lh=mh=0$), ($nh=1;lh=mh=0$), ($nh=2;lh=mh=0$), ($nh=3;lh=mh=0$) (here $lh$, $mh$ are the orbital and magnetic quantum numbers of an hole), to the lowest electron size – quantized level ($ne=1$, $le=me=0$), we have Display Formula
$K(s\xaf,\omega )A=L1(s\xaf)+L2(s\xaf)+L3(s\xaf),$(3)
where $L0=1.639\u2009\u2009s\xaf\u22123/4$, $L1=0.5\u2009\u2009L0$, $L2=9.38\xb710\u22122\u2009\u2009L0$, $L3=10\u22122L0$. From the above expression, it follows that the main contribution in the light absorption coefficient is a cadmium sulphide QD from the hole spectral lines corresponding to quantum numbers ($nh=0$; $lh=mh=0$) and ($nh=1$; $lh=mh=0$) the transition oscillator strengths of which are dominant.^{1} The contribution of higher exited hole lines ($nh\u22652$; $lh=mh=0$) is negligible.
