Experimental study of the Si-30(He-3, d) P-31 reaction and thermonuclear reaction rate of Si-30(p, gamma)( 3)1P
PHYSICAL REVIEW C, 105(1).
Element abundance anomalies in globular star clusters may be used to understand their history and to identify the nature of the stars responsible for these anomalies. The ${}^{30}$Si($p$,$\ensuremath{\gamma}$)${}^{31}$P thermonuclear rate is a key ingredient in addressing that topic, and a high-resolution indirect measurement of this radiative proton-capture reaction has been undertaken at relevant stellar temperatures. The strength of key resonances has been determined, and the major contributions to the remaining uncertainty are now well known.
