<span style="color:rgb(32,31,30); font-size:15px">1) In Fig. 2.b, they fixed the energy of the second peak to be 709 keV lower than the main one, but the centroids obviously do not agree (50 keV off?). Why not let it vary free?</span><br>

2) They claim a 63% branching from Sr-73 to Br-73*(IAS). Where does this number come from? Where is the other 37% decay going to? (see Fig. 3)</div>
<div style="margin:0px; font-size:15px; color:rgb(32,31,30); background-color:rgb(255,255,255)">

<div style="margin:0px; font-size:15px; color:rgb(32,31,30); background-color:rgb(255,255,255)">
3) How do they know that Sr-73 is decaying from the ground state? The doublet in Br-73 is 27 keV, if here it is smaller (1-5 keV) the higher-energy isomer could beta decay with a similar half-life.</div>

4) What is so relevant about this result, this is not the first case of isospin symmetry breaking, it's not the strongest and it's model dependant?<br>
<div style="margin:0px"><br>
</div>
<div style="margin:0px">5) Any wild guesses on why neighbouring odd-odd N=Z isotopes have 0+ g.s (i.e. no isospin symmetry violation)?</div>
<div style="margin:0px">FOLLOW UP: and why most A<40 odd-odd N=Z isotopes do NOT have 0+ g.s?</div>
<div style="margin:0px"><br>
</div>
<div style="margin:0px">TRICK QUESTION: why can't you have a T_z=+1,-1 and T=0 state?<br>

<div style="margin:0px">BONUS QUESTION: why do you think Nature (arguably the most prestigious journal in science) has such a terrible layout?</div>
