WebDec 10, 2024 · In this Letter, we focus on the effect of shell evolution on Gamow-Teller (GT) transitions, which dominate the β decay in the south-west region of the doubly magic nucleus 132 Sn. The experimental probe is a previously unreported high-spin isomer in 127 Ag (proton number Z = 47 and N = 80 ), which enables an exploration of the daughter … WebBackground: Gamow-Teller (GT) transition strengths are key inputs for estimating weak reaction rates of importance for a wide variety of astrophysical applications. (n,p)-type charge-exchange reactions, such as the (t,3He) reaction used in this work, are commonly used for extracting the GT strength distribution in the β+

WebThe beta-decay strength for the weak Gamow-Teller ' transition to the ground state of 51 Cr has been measured to have log ft = 5.3893 ± 0.0016 [Aub 78]. The JP = r ground state of 51 Cr is well separated from the other excited states, and the transition from the ~ - ground state in 51 V can be measured Webthat represents the transitions of nucleons, as really transitions between the up (u) and down (d) quarks. A particle physics picture of β−-decay is given in Figure 15.2. Figure 15.2: The particle physics view of β−-decay. In this case, the weak force is carried by the intermediate vector boson, the W−.

The nucleus studied was 14O, and the Gamow-Teller transition strength to N was extracted up to an excitation energy of 22 MeV. The measurement of the (d;2He) reaction in inverse kinematics was made possible
WebGamow and Teller (1936) soon proposed a modification of Fermi’s vector theory. Fermi’s theory had originally required a selection rule, the change in \(J = 0\), where \(J\) is the angular momentum of the nucleus, and did not include the effects of nuclear spin. ...
