A novel technique has been developed, which will open exciting new opportunities for studying the very neutron-rich nuclei involved in the r process. As a proof of principle, the γ spectra from the β decay of ^{76}Ga have been measured with the SuN detector at the National Superconducting Cyclotron Laboratory. The nuclear level density and γ-ray strength function are extracted and used as input to Hauser-Feshbach calculations. The present technique is shown to strongly constrain the ^{75}Ge(n…

Indirect, experimental constraints of (n,γ) reaction rates for the i- and r-process

Our Universe contains a large variety of chemical elements, for which only the lightest ones were produced during the Big Bang. To make elements heavier than iron, neutron-capture processes are

Constraining Neutron Capture Cross Sections for Unstable Nuclei with Surrogate Reaction Data and Theory.

A new method for determining cross sections for neutron capture on unstable isotopes, using ^{87}Y(n,γ) as a prototype, is demonstrated, which can be generalized to a larger class of nuclear reactions.

Compound-nuclear reactions with unstable nuclei: Constraining theory through innovative experimental approaches

Cross sections for compound-nuclear reactions involving unstable targets are important for many applications, but can often not be measured directly. Several indi- rect methods have recently been

Towards Neutron Capture on Exotic Nuclei: Demonstrating (d,pγ) as a Surrogate Reaction for (n,γ).

A new technique is demonstrated which can be used to indirectly determine neutron-capture cross sections for exotic systems, using the (d,p) transfer reaction, which has long been used as a tool to study the structure of nuclei.

One-nucleon pickup reactions and compound-nuclear decays

One-nucleon transfer reactions, long used as a tool to study the structure of nuclei, are potentially valuable for determining reaction cross sections indirectly. This is significant, as many

Abstract.Photon strength functions describing the average response of the nucleus to an electromagnetic probe are key input information in the theoretical modelling of nuclear reactions. Consequently

Capture cross sections from (p,d) reactions

Cross sections for compound-nuclear reactions involving unstable targets are important for many applications, but can often not be measured directly. Several indirect methods have been proposed to

First evidence of low energy enhancement in Ge isotopes

The γ-strength functions and level densities of 73,74 Ge have been extracted from particle-γ coincidence data using the Oslo method. In addition the γ-strength function of 74 Ge above the neutron

Experimental Neutron Capture Rate Constraint Far from Stability.

This work reports on the first experimental extraction of a neutron capture reaction rate on Ni, a nucleus that is five neutrons away from the last stable isotope of Ni, and the implications on nucleosynthesis around mass 70 are discussed.

How do we infer shell effects at high-excitation energies? A new spectroscopic probe to search for magic numbers

The nuclear dipole polarizability is mainly governed by the dynamics of the giant dipole resonance and, assuming validity of the brink-Axel hypothesis, has been investigated along with the effects of
