Title: New energy for the 133-keV resonance in the ²³Na(p,γ) ²⁴Mg reaction and its impact on nucleosynthesis in globular clusters

Abstract

Globular cluster stars exhibit star-to-star anticorrelations between oxygen and sodium in their atmospheres. An improved description of the sodium-destroying ²³Na +p reaction rates is essential to understanding these observations. We present an energy analysis of ²⁴Mg states based on a new measurement of the ²³Na(³He, d) ²⁴Mg reaction. A key resonance in ²³Na(p, γ) ²⁴Mg is found to be at $$E$$ $$^{c.m.}_{r}$$ = 133(3) keV, 5 keV lower than previously adopted. This finding has a dramatic effect on the ²³Na(p, γ) ²⁴Mg reaction rate, increasing it by a factor of 2 for the recommended rate. Furthermore, the nucleosynthesis impact of this change is investigated.

New constraints on sodium production in globular clusters from the Na 23 ( He 3 , d ) Mg 24 reaction

Journal Article Marshall, C. ; Setoodehnia, K. ; Cinquegrana, G. C. ; ... - Physical Review. C

The star-to-star anticorrelation of sodium and oxygen is a defining feature of globular clusters, but, to date, the astrophysical site responsible for this unique chemical signature remains unknown. Sodium enrichment within these clusters depends sensitively on reaction rate of the sodium destroying reactions ²³Na(p, γ) and ²³Na(p,α). In this paper, we report the results of a ²³Na(³He,d)²⁴Mg transfer reaction carried out at Triangle Universities Nuclear Laboratory using a 21 MeV ³He beam. Astrophysically relevant states in ²⁴Mg between 11 < E_x < 12 MeV were studied using high-resolution magnetic spectroscopy, thereby allowing the extraction of excitation energies and spectroscopic factors.more »« less

Searching for resonance states in Ne 22 ( p , γ ) Na 23

Journal Article Carrasco-Rojas, D. P. ; Williams, M. ; Adsley, P. ; ... - Physical Review. C

Globular clusters show strong correlations between different elements, such as the well-known sodium-oxygen anticorrelation. One of the main sources of uncertainty in this anticorrelation is the ²²Ne(p,γ)²³Na reaction rate, due to the possible influence of an unobserved resonance state at E_x = 8862 keV (E_r,c.m.=68 keV). The influence of two higher-lying resonance states at E_x = 8894 and 9000 keV has already been ruled out by direct ²²Ne(p,γ)²³Na measurements. To study excited states in ²³Na above the proton threshold to determine if the unconfirmed resonance states in ²³Na exist.

Investigation of the {sup 23}Na(p,{gamma}){sup 24}Mg and {sup 23}Na(p,{alpha}){sup 20}Ne reactions via ({sup 3}He,d) spectroscopy

Journal Article Hale, S E ; Champagne, A E ; Iliadis, C ; ... - Physical Review. C, Nuclear Physics

States near the {sup 23}Na+p threshold in {sup 24}Mg were investigated using the {sup 23}Na({sup 3}He,d){sup 24}Mg reaction over the angular range of 5 deg. {<=}{theta}{sub lab}{<=}35 deg. at E({sup 3}He)=20 MeV. Spectroscopic factors were extracted for states corresponding to resonances in the {sup 23}Na(p,{gamma}){sup 24}Mg and {sup 23}Na(p,{alpha}){sup 20}Ne reactions. We find that one state, corresponding to a previously unobserved resonance at E{sub c.m.}=138 keV, may make a significant contribution to the rates of both reactions at low temperatures. Another state, corresponding to a possible resonance at E{sub c.m.}=37 keV may make a small contribution to the {sup 23}Na(p,{alpha}){supmore »« less

High Resolution Study of 40Ca to Constrain Potassium Nucleosynthesis in NGC 2419

Journal Article Fox, William ; Longland, Richard ; Marshall, Caleb ; ... - Physical Review Letters

The globular cluster NGC 2419 was the first to exhibit a Mg-K anticorrelation, linked to hydrogen burning at temperatures between 80-260 MK. However, the key K-destroying reaction, 39K(p,γ)40Ca, has a large rate uncertainty in this range. We significantly constrain this rate with a high resolution 39K(3He,d)40Ca study. We resolve the Ec.m.r=154 keV resonance in 39K+p for the first time, increasing the previous rate by up to a factor 13 and reducing its 1σ width by up to a factor of 42. Reaction network calculations for NGC 2419 suggest that this could lower temperatures needed to reproduce the Mg-K anticorrelation.
