Mk. Cheoun et al., A CURRENT-ALGEBRA MODEL IN PHOTOPION PRODUCTION FOR THE 3-BODY NUCLEUS, Journal of the Korean Physical Society, 28(1), 1995, pp. 1-6
A current algebra model is presented for nuclear photopion production.
The elementary particle method (EPM) of this model achieves good agre
ement with the experimental results for He-3(gamma, pi+) H-3 in the re
gion below the DELTA resonance. We compare our calculations with the r
esults of the EPM based on the Born terms. The results of the impulse
approximation are also compared to the results of both EPM calculation
