چکیده

C. C. Foster Indiana Uni versity Cyclotron Facility, Bloomington, Indiana 47405 (Received 12 July 1985) Gamow-Teller transition probabilities are extracted for eight nuclei with masses between 3 = 13 and 39 from medium-energy (p, n) reactions via the distorted-wave impulse approximation, and compared with experimental P-decay and with free-nucleon transition probabilities. These comparisons indicate strongly that the renormalization of the Gamow-Teller operator needed for (p, n) reactions on finite nuclei is different from that needed for P decay.

57%o REACTIONS AT EP = 120 MeV

Differential cross sections for the (p, n) reaction on ‘*,%r and 57,5XFe have been measured for angles up to Slirh = X0.5” and 14.6”, respectively, using 120 MeV protons. The observed angular distributions are used to evaluate the location and strength of Gamow-Teller resonances. A shell-model calculation of this strength distribution is presented and compared with the experimental results. The...

Fermi and Gamow-Teller Strength in Charge Exchange with Radioactive Beams

At forward angles, and bombarding energies E > 200 MeV, the (p, n) and (n, p) reactions are thought to be directly proportional to the Gamow-Teller transition strengths in the nuclei. Assuming that this relationship also holds for charge exchange induced by high-energy heavy ions, it would be very useful in studies with radioactive beams. Contrary to this expectation, we show that the determina...

Probing configuration mixing in 12Be with Gamow-Teller transition strengths.

We present a novel technique for studying the quenching of shell gaps in exotic isotopes. The method is based on extracting Gamow-Teller (ΔL=0, ΔS=1) transition strengths [B(GT)] to low-lying states from charge-exchange reactions at intermediate beam energies. These Gamow-Teller strengths are very sensitive to configuration mixing between cross-shell orbitals, and this technique thus provides a...

We present Gamow-Teller strength distributions from shell model Monte Carlo studies of fp-shell nuclei that may play an important role in the precollapse evolution of supernovae. We then use these strength distributions to calculate the electron-capture cross sections and rates in the zero-momentum transfer limit. We also discuss the thermal behavior of the cross sections. We find large differe...
