<h2><a name="details" id="details"></a>Detailed Description</h2>
<p>The <code>FrangibleNucleus</code> class represent a nucleus in Sartre,
inheriting all descriptive features form <a href="refNucleus.html">Nucleus</a>.
The user
does not have to care about the class or its initialization since it
is all handled internally in
<a href="refSartre.html">Sartre</a>. However, the actual instance of
this class is always accessible through <a href="refSartre.html#nucleus">Sartre::nucleus()</a>.
After an incoherent event is generated <strong>and</strong> nuclear
breakup is switched on (via <a href="runcardRef.html#enableNuclearBreakup">runcard</a> or <a href="refEventGeneratorSettings.html#setEnableNuclearBreakup">programmatically</a>)
the breakup products are stored in the <a href="refEvent.html">event
record</a>. More information about the nucleus and the breakup can
be obtained through an instance of this class which can be obtained
from the class <a href="refSartre.html">Sartre</a>
via <a href="refSartre.html#nucleus">Sartre::nucleus()</a>.

<h2>Public Member Function Documentation</h2>
<h3 class="fn"><span class="memItemRight"><a name="FrangibleNucleus" id="FrangibleNucleus"></a> FrangibleNucleus() </span></h3>
<p>Constructor. Creates an uninitialized object. Requires a call to<a href="#init2"> init()</a> in
order to represent a valid nucleus.</p>
<h3 class="fn"><span class="memItemRight"><a name="FrangibleNucleus" id="FrangibleNucleus"></a> FrangibleNucleus(const
FrangibleNucleus&amp; <var>nucleus</var>) </span></h3>
<p>Copy constructor.</p>
<h3 class="fn"><span class="memItemRight"><a name="FrangibleNucleus" id="FrangibleNucleus"></a> FrangibleNucleus(unsigned int <var>A</var>, bool enableBreakup = <var>false</var>) </span></h3>
<p>Constructor. Creates a nucleus with mass <var>A</var>, and allows to enable
or disable (default) nuclear breakup.</p>
<h3 class="fn"><span class="memItemRight"><a name="~FrangibleNucleus" id="~FrangibleNucleus"></a> ~FrangibleNucleus() </span></h3>
<p>Destructor.</p>
<h3 class="fn"><span class="memItemRight"><a name="operator=" id="operator="></a> FrangibleNucleus&amp; operator=(const
FrangibleNucleus&amp; <var>nucleus</var>) </span></h3>
<p>Assignment operator.</p>
<h3 class="fn"><span class="memItemRight"><a name="#init2" id="#init2"></a> void
init(unsigned int <var>A</var>, bool enableBreakup = <var>false</var>) </span></h3>
<p>Initializes the object created via the default <a href="#FrangibleNucleus">constructor</a> (w/o
arguments). Not needed when constructor with same arguments as init() was used.</p>
<h3 class="fn"><span class="memItemRight"><a name="breakup" id="breakup"></a> int
breakup(const TLorentzVector&amp; <var>vec</var>) </span></h3>
<p>Breakup nucleus into fragments using the Gemini++ model. <var>vec</var> is
the 4-momentum
of the nucleus. The breakup itself is calculated in the nucleus rest
frame but the breakup products are boosted according to <var>vec</var>.
Returned value is the number of generated fragments.</p>
<h3 class="fn"><span class="memItemRight"><a name="breakupProducts" id="breakupProducts"></a> const
vector&lt;<a href="refBreakupProduct.html">BreakupProducts</a>&gt;
<BreakupProducts>&amp; breakupProducts() const </span></h3>
<p>Returns vector with fragments generated with <a href="#breakup">breakup()</a>.</p>
<h3 class="fn"><span class="memItemRight"><a name="listBreakupProducts" id="listBreakupProducts"></a> void
listBreakupProducts(ostream&amp; <var>os</var> = cout) const</span></h3>
<p>Prints list of all breakup products to ostream <var>os</var>. If no
argument is given it prints to <code>stdout</code>. Prints name of
fragment, A, Z, PDG identifier, time of emission in NP units, and
px, py, pz, and E (in GeV/c and GeV). The emission time is given
in units of 10<sup>-21</sup> seconds since the creation
of the compound nucleus in the nucleus rest frame. These are typical
NP units as used in Gemini++. Note that here the 4-momentum is that
of the fragment and is <strong>not</strong> scaled to &quot;per nucleon&quot; as
is done in the event record.</p>
