An Analysis of the <sup>18</sup>F<sup>g,m</sup>(d,p)<sup>19</sup>F reactions in the Rotational Model.

ORAL

Abstract

In a recent HELIOS[1] measurement, the (d,p) reaction on 18F, from both the ground (1+) and isomeric (5+) states [2] was used to study members of the ground-state rotational band in 19F.

Comparison of the derived  Spectroscopic Factors  with shell model calculations within the sd shell, provided a nice confirmation of the single-particle–collective duality observed in the structure of atomic nuclei.

In this work we exploit this apparent duality in an analysis of the their experimental results in terms of the rotational model.   We consider the structure of  18,19F in terms of Nilsson single-particle orbits originating from the sd spherical levels and calculate the (d,p) spectroscopic strengths to 19F  from both the ground and isomeric states following the framework reviewed in [3].

Perhaps not surprisingly, our results show good agreement with the experiment and the shell model.
