A direct measurement of the 17O(a,g)21Ne reaction in inverse kinematics and its impact on heavy element production
M. P. Taggart, C. Akers, A. M. Laird +33
During the slow neutron capture process in massive stars, reactions on light elements can both produce and absorb neutrons thereby influencing the final heavy element abundances. A…
Shell evolution approaching the N=20 island of inversion: Structure of 29Mg
A. Matta, W. N. Catford, N. A. Orr +36
The "Island of Inversion" for neutron-rich nuclei in the vicinity of N=20 has become the testing ground par excellence for our understanding and modelling of shell evolution with i…
The Nab Experiment: A Precision Measurement of Unpolarized Neutron Beta Decay
J. Fry, R. Alarcon, S. Baessler +69
Neutron beta decay is one of the most fundamental processes in nuclear physics and provides sensitive means to uncover the details of the weak interaction. Neutron beta decay can e…
Measurement of the neutron lifetime using a magneto-gravitational trap
Nathan Callahan
Precision measurements of the free neutron lifetime , when combined with measurements of the axial vector form factor, can be used to test unitarity of the CKM matrix. Non-uni…
Measurement of the neutron lifetime using an asymmetric magneto- gravitational trap and in situ detection
R. W. Pattie, N. B. Callahan, C. Cude-Woods +35
The precise value of the mean neutron lifetime, , plays an important role in nuclear and particle physics and cosmology. It is a key input for predicting the ratio of protons…
A new method for measuring the neutron lifetime using an in situ neutron detector
C. L. Morris, E. R. Adamek, L. J. Broussard +28
The neutron lifetime is important in understanding the production of light nuclei in the first minutes after the big bang and it provides basic information on the charged weak curr…
Shell evolution approaching the N=20 island of inversion: structure of 26Na
G. L. Wilson, W. N. Catford, N. A. Orr +37
The levels in 26Na with single particle character have been observed for the first time using the d(25Na,p gamma) reaction at 5 MeV/nucleon. The measured excitation energies and th…
Two-neutron transfer reaction mechanisms in C(He,He)C using a realistic three-body He model
D. Smalley, F. Sarazin, F. M. Nunes +33
The reaction mechanisms of the two-neutron transfer reaction C(He,He) have been studied at 30 MeV at the TRIUMF ISAC-II facility using the SHARC charged-particle det…
Measurements of ultracold neutron upscattering and absorption in polyethylene and vanadium
E. I. Sharapov, C. L. Morris, M. Makela +27
The study of neutron cross sections for elements used as efficient ``absorbers'' of ultracold neutrons (UCN) is crucial for many precision experiments in nuclear and particle physi…
High-Precision Measurement of the 19Ne Half-Life and Implications for Right-Handed Weak Currents
S. Triambak, P. Finlay, C. S. Sumithrarachchi +21
We report a precise determination of the 19Ne half-life to be s. This result disagrees with the most recent precision measurements and is important for…
Measurement of the 18Ne(a,p_0)21Na reaction cross section in the burning energy region for X-ray bursts
P. J. C. Salter, M. Aliotta, T. Davinson +14
The 18Ne(a,p)21Na reaction provides one of the main HCNO-breakout routes into the rp-process in X-ray bursts. The 18Ne(a,p_0)21Na reaction cross section has been determined for the…
The 3He + 4He --> 7Be Astrophysical S-factor
