Deuteron D‐State Helps Explain J Dependence in p,d Reaction
DOI: 10.1063/1.3034928
The type of spin dependence in direct nuclear reactions that was found in 1964 by Rubby Sherr, Ernest Rost and Martin Rickey appears to be explained well by some recent calculations of R. C. Johnson and Filipe D. Santos of the University of Surrey (reported at the Tokyo Nuclear Structure conference). The theorists, using the distorted‐wave Born approximation, calculated cross section as a function of angle for p,d and d,p reactions. They found that, although the deuteron wave function is predominantly Sstate, one must also include D‐state contributions in the calculation to account for the forward‐angle variation of deuteron angular distributions with the spin J of the final nucleus. Largeangle spin dependence, also discovered in 1964 by Linwood Lee Jr and John Schiffer, awaits explanation.
