Hi everyone,<br>
<br>
after the excursion into astrophysics last week, we'll return to
good old nuclear structure in next week's journal club. We'll be
discussing the article "<span class="title-text">Single-neutron
knockout from <sup>20</sup>C and the structure of <sup>19</sup>C"
(<a class="moz-txt-link-freetext" href="https://www.sciencedirect.com/science/article/pii/S0370269317302939">https://www.sciencedirect.com/science/article/pii/S0370269317302939</a>).
And if the thought of discussing a fascinating if slightly
technical experimental paper isn't enough for you, there will also
be snacks, as usual provided by our loving and beloved GAPS.</span><br>
<br>
Questions:<br>
What is the motivation given for studying drip-line nuclei in
general and ¹⁹C in particular?<br>
How is the relative energy between neutron and fragment E_rel
obtained? Which detectors are used for that?<br>
What background contributions are taken into account?<br>
How are spin and parity of the observed states assigned?<br>
What explanation is given for the theoretical calculations
predicting the states in the wrong order? <br>
<br>
Also, for people unfamiliar with the topic, looking up the answers
to the following questions might help understanding:<br>
<br>
What is a halo nucleus?<br>
What is eikonal reaction theory?<br>
What are spectroscopic factors?<br>
<br>
Cheers,<br>
Matthias<br>
