Measuring the cross section of the N(,)F reaction using a single-fluid bubble chamber
D. Neto, K. Bailey, J. F. Benesch +17
N(,)F is believed to be the primary means of stellar nucleosynthesis of fluorine. Here we present the use of a single-fluid bubble chamber to measure the cross…
Study of the Mg waiting point relevant for x-ray burst nucleosynthesis via the Mg(,)Al reaction
H. Jayatissa, M. L. Avila, K. E. Rehm +13
The Mg(,)Al reaction rate has been identified as a major source of uncertainty for understanding the nucleosynthesis flow in Type-I x-ray bursts (XRBs). We repo…
Study of the astrophysically important and reactions
M. L. Avila, K. E. Rehm, S. Almaraz-Calderon +11
The NaMg and NaAl reactions are important for our understanding of the Al abundance in massive stars. The aim of this work is to report…
Study of and reactions with a Multi-Sampling Ionization Chamber
M. L. Avila, K. E. Rehm, S. Almaraz-Calderon +11
A large number of and reactions are known to play a fundamental role in nuclear astrophysics. This work presents a novel technique to study these reactions with the…
Independent measurement of the Hoyle state feeding from 12B using Gammasphere
M. Munch, M. Alcorta, H. O. U. Fynbo +28
Using an array of high-purity Compton-suppressed germanium detectors, we performed an independent measurement of the -decay branching ratio from to the second-…
Bubble Chambers for Experiments in Nuclear Astrophysics
B. DiGiovine, D. Henderson, R. J. Holt +7
A bubble chamber has been developed to be used as an active target system for low energy nuclear astrophysics experiments. Adopting ideas from dark matter detection with superheate…
Fusion reactions with the one-neutron halo nucleus 15C
M. Alcorta, K. E. Rehm, B. B. Back +15
The structure of 15C, with an s1/2 neutron weakly bound to a closed-neutron shell nucleus 14C, makes it a prime candidate for a one-neutron halo nucleus. We have for the first time…
The neutron long counter NERO for studies of beta-delayed neutron emission in the r-process
J. Pereira, P. Hosmer, G. Lorusso +23
The neutron long counter NERO was built at the National Superconducting Cyclotron Laboratory (NSCL), Michigan State University, for measuring beta-delayed neutron-emission probabil…
The Ne(,n)Mg neutron source: latest experimental results and prospects
Claudio Ugalde
The current status of the reaction rate of Ne(,n)Mg is summarized. Among the latest new results, probably the most relevant is the conclusion that the E=11.15…
The thermonuclear rate for the 19F(a,p)22Ne reaction at stellar temperatures
Claudio Ugalde, Richard Azuma, Aaron Couture +6
The F(,p)Ne reaction is considered to be one of the main sources of fluorine depletion in AGB and Wolf-Rayet stars. The reaction rate still retains large uncertain…
Experimental evidence of a natural parity state in Mg and its impact to the production of neutrons for the s process
C. Ugalde, A. E. Champagne, S. Daigle +9
We have studied natural parity states in Mg via the Ne(Li,d)Mg reaction. Our method significantly improves the energy resolution of previous experiments…
