TL;DR: In this paper, the (p, n) reactions on several targets from 40Ca to 208Pb have been studied at 200 MeV using the Indiana University Cyclotron time-of-flight facilities.
Journal ArticleDOI
Gamow-Teller strength of 90 Nb in the continuum studied via multipole decomposition analysis of the 90 Zr ( p , n ) reaction at 295 MeV

TL;DR: In this article, a multipole decomposition technique is applied to the double differential cross sections to extract $L=0, $L = 1,$L=2, and $L < 3$ contributions.
Journal ArticleDOI

TL;DR: In this paper, a multipole decomposition technique was applied to the present data as well as the previously obtained 90 Zr(p, n) data to extract the Gamow-Teller (GT) component from the continuum.
Journal ArticleDOI

TL;DR: In this paper, the authors compared the experimental results with theoretical results based on Faddeev calculations with realistic nucleon-nucleon ($\mathit{NN}$) forces such as AV18, CD Bonn, and Nijmegen I and II, and their combinations with the three nucleon forces (3NFs), such as Tucson-Melbourne 99 (TM99), Urbana IX, and the coupled channel potential with \ensuremath{\Delta}-isobar excitation.
Journal ArticleDOI
Gamow-teller strength distributions in Sc48 by the Ca48(p,n) and Ti48(n,p) reactions and two-neutrino double-β decay nuclear matrix elements

TL;DR: The double-differential cross sections for the 48Ca(p,n) and 48Ti(n,p) reactions were measured at 300 MeV and additional GT strengths were found above 8 MeV, suggesting that the present shell-model description of the nuclear matrix element of the two-neutrino double-beta decay is incomplete.
