Abstract

Precision measurements were carried out to test the similarities between the ground states of Ge76 and Se76. The extent to which these two nuclei can be characterized as consisting of correlated pairs of neutrons in a BCS-like ground state was studied. The pair removal (p,t) reaction was measured at the far forward angle of 3°. The relative cross sections are consistent (at the 5% level) with the description of these nuclei in terms of a correlated pairing state outside the N=28 closed shells with no pairing vibrations. Data were also obtained for Ge74 and Se78. © 2007 The American Physical Society.
