<strong>Symmetries</strong><br />

From sp<strong>in</strong> to isosp<strong>in</strong><br />

Dynamical implications: Bound states (deuteron)<br />

Add two nucleons: can have isos<strong>in</strong>glet and isotriplet.<br />

No pp, nn-bound states deuteron = isos<strong>in</strong>glet !!!<br />

Consider processes (+ their isosp<strong>in</strong> amplitudes, below)<br />
