ABSTRACT=<p>The determination of the <inline-formula id="inf1"><mml:math id="m1" xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:mrow><mml:mi>β</mml:mi></mml:mrow></mml:math></inline-formula> intensity probability between the ground states of parent and daughter nuclei has traditionally been a difficult task with standard <inline-formula id="inf2"><mml:math id="m2" xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:mrow><mml:mi>γ</mml:mi></mml:mrow></mml:math></inline-formula>-spectroscopy approaches due to the lack of the associated <inline-formula id="inf3"><mml:math id="m3" xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:mrow><mml:mi>γ</mml:mi></mml:mrow></mml:math></inline-formula> emission. In the last years, the total absorption <inline-formula id="inf4"><mml:math id="m4" xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:mrow><mml:mi>γ</mml:mi></mml:mrow></mml:math></inline-formula>-ray spectroscopy technique has successfully proven its ability to deal with this problem by means of different procedures. This article discusses the potential of these methods, and a new approach for segmented total-absorption <inline-formula id="inf5"><mml:math id="m5" xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:mrow><mml:mi>γ</mml:mi></mml:mrow></mml:math></inline-formula>-ray spectrometers is also introduced. An overview of applications is presented based on past, present, and future <inline-formula id="inf6"><mml:math id="m6" xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:mrow><mml:mi>β</mml:mi></mml:mrow></mml:math></inline-formula>-decay experiments.</p>
