The spin degree of freedom in nuclei: levels and transitions in 58Cu

Gamow-Teller (GT) transitions in the region of A=56 are described in terms of the coupling between isovector and isoscalar pairing phonons and Gamow-Teller excitations. The available experimental information is used to extract coupling constants and strength functions of addition (removal) isoscalar...

Description
Summary:Gamow-Teller (GT) transitions in the region of A=56 are described in terms of the coupling between isovector and isoscalar pairing phonons and Gamow-Teller excitations. The available experimental information is used to extract coupling constants and strength functions of addition (removal) isoscalar and isovector pairing phonons and GT phonons. The validity of the approach is tested by the calculation of intensities for GT transitions in 58Cu.
