Hb. Vandenbrink et al., THE C-13(GAMMA,PI(-))N-13 REACTION AT E-GAMMA-APPROXIMATE-TO-184 MEV (T-PI-APPROXIMATE-TO-41 MEV), Nuclear physics. A, 587(4), 1995, pp. 657-674
Differential cross sections for the C-13(gamma, pi(-))N-13 reaction at
E(gamma) approximate to 184 MeV (T-pi approximate to 41 MeV) were mea
sured with the Saskatoon tagged-photon facility and two range-telescop
e detectors. Data were obtained at pion angles of 45 degrees, 60 degre
es, 80 degrees and 100 degrees, with emphasis on the forward angles, w
here the cross section shows a strong rise. The present data, together
with existing ones at larger angles, are compared to several theoreti
cal calculations.
