A stringent upper limit on the direct 3 decay of the Hoyle State in C

Moshe Gai
Rijal, et al. in their recent publication [Phys. Rev. Lett {\bf 122}, 182701 (2019), arXiv:1808.07893], on "Measurement of d + Be Cross Sections for Big-Bang Nucleosynthesis (B…
Gai Reply to Comment by Schumann et al. (arXiv:1904.03023v1)
Moshe Gai
Statements included in the comment published by Schumann et al. (arXiv:1904.03023v1) are contradicted by documents that were communicated to one of the co-authors of the comment (D…
The Interaction of Neutrons With 7Be: Lack of Standard Nuclear Physics Solution to the "Primordial 7Li Problem"
Moshe Gai
The destruction of 7Be with neutrons represents the last possible standard avenue to reduce the predicted abundance of the primordial 7Li and in this way to attempt to solve the Co…
On the sensitivity of extracting the astrophysical cross section factor of the 12C(a,g) reaction from existing data [Comment on Schuermann et al. Phys. Lett. B711(2012)35]
Moshe Gai
We address a conflicting report on the value and uncertainty of the astrophysical cross section factor of the 12C(a,g) reaction extracted from existing data. In sharp contrast to p…
Evidence for Triangular D_3h Symmetry in 12C
D. J. Marin-Lambarri, R. Bijker, M. Freer +4
We report a measurement of a new high spin Jp = 5- state at 22.4(0.2) MeV in 12C which fits very well to the predicted (ground state) rotational band of an oblate equilateral trian…
Nuclear Structure and the Fate of Core Collapse (Type II) Supernova
Moshe Gai
For a long time Gerry Brown and his collaborator Hans Bethe considered the question of the final fate of a core collapse (Type II) supernova. Recalling ideas from nuclear structure…
Ambiguities of the Rate of Oxygen Formation During Stellar Helium Burning in the 12C(a,g) Reaction
Moshe Gai
The rate of oxygen formation determines the C/O ratio during stellar helium burning. It is the single most important nuclear input of stellar evolution theory including the evoluti…
Unambiguous Identification of the Second 2+ State in 12C and the Structure of the Hoyle State
W. R. Zimmerman, M. W. Ahmed, B. Bromberger +11
The second 2+ state of 12C, predicted over fifty years ago as an excitation of the Hoyle state, has been unambiguously identified using the 12C(g,a_0)8Be reaction. The alpha partic…
Solar fusion cross sections II: the pp chain and CNO cycles
E. G. Adelberger, A. B. Balantekin, D. Bemmerer +45
We summarize and critically evaluate the available data on nuclear fusion cross sections important to energy generation in the Sun and other hydrogen-burning stars and to solar neu…
The Dissociation of 8B in the Coulomb Field and the Validity of the CD Method
Moshe Gai
The GSI1, GSI2 (as well as the RIKEN2 and the corrected GSI2) measurements of the Coulomb Dissociation (CD) of 8B are in good agreement with the most recent Direct Capture (DC) 7Be…
A Further Measurement of the beta-Delayed alpha-Particle Emission of 16N
R. H. France, E. L. Wilds, J. E. McDonald +1
We measured the beta-delayed alpha-particle emission spectrum of 16N with a sensitivity for beta-decay branching ratios of the order of 10-10. The 16N nuclei were produced using th…
In Beam Tests of Implanted Helium Targets
J. E. McDonald, R. H. France, R. A. Jarvis +22
Targets consisting of 3,4He implanted into thin aluminum foils (approximately 100, 200 or 600 ug/cm^2) were prepared using intense (a few uA) helium beams at low energy (approximat…
Production of Fast Neutron With Plasma Focus Device
Moshe Gai
Before its demise DIANA Hi-TECH, LLC, demonstrated the use of two 50 kJoule Plasma Focus devices for the copius production of fast neutrons, x-rays and radio-isotopes. Such a devic…
The Coulomb Dissociation of 8B; A Triumph of Good Science
Moshe Gai
The GSI1, GSI2 (as well as the RIKEN2 and the corrected GSI2) measurements of the Coulomb Dissociation (CD) of 8B are in good agreement with the most recent Direct Capture (DC) 7Be…
Status of the Standard Solar Model Prediction of Solar Neutrino Fluxes
Moshe Gai
The Standard Solar Model (BP04) predicts a total 8B neutrino flux that is 17.2% larger than measured in the salt phase of the SNO detector (and if it were significant it will indic…
Comment on Esbensen, Bertsch and Snover Concerning Reconciling Coulomb Dissociation and Radiative Capture Measurements
Moshe Gai
The RIKEN data on the Coulomb Dissociation (CD) of 8B were shown to be in good agreement with the Direct Capture (DC) data on the 7Be(p,g)8B reaction (that were known at that time)…
Optical Readout Time Projection Chamber (O-TPC) for a Study of Oxygen Formation In Stellar Helium Burning
Moshe Gai, Amos Breskin, Rachel Chechik +2
We are developing an Optical Readout Time Projection Chamber (O-TPC) detector for the study of the 12C(a,g)16O reaction that determines the ratio of carbon to oxygen in helium burn…
Is There a Significant Difference Between the Results of the Coulomb Dissociation of 8B and the Direct Capture 7Be(p,g)8B Reaction?
Moshe Gai
Recent claims of the Seattle group of evidence of "slope difference between CD [Coulomb Dissociation] and direct [capture] results" are based on wrong and selective data. When the…
Do We Accurately Know the Formation of Solar 8B?
Moshe Gai
A detailed examination of current data on S_17 (as opposed to an examination of S_17(0) only) excludes quoting S_17(0) with sufficiently small uncertainty. In contrast to suggestio…

M. Mirazita, The CLAS collaboration
Nearly complete angular distributions of the two-body deuteron photodisintegration differential cross section have been measured using the CLAS detector and the tagged photon beam…
The Coulomb Dissociation of 8B and a Critical Assessment of the Seattle S17(0) Result
Moshe Gai

Comment on B. Davids et al.; Proton-Decaying States in 22Mg and the Nucleosynthesis of 22Na in Novae
Moshe Gai
B.S. Davids {\em et al.} make the explicit assumption that radiative widths of analog states in \ne22 and \mg22 are equal. We demonstrate that this misapplication of iso-spin symme…
How Accurately Do We Know the Formation of Solar 8B?
Moshe Gai
The large value of \S17 = 22.1 \xpm 0.6 eV-b, reported by the Seattle group, suggests a larger total \b8 solar neutrino flux. Together with the two high precision values quoted for…
