779Relativistic analyses of the ratio of the isovector spin-flip to nonspin-flip effective NN interaction strength from the Gamow-Teller and Fermi transitions in O' (p, n) scattering are performed using the factorized relativistic distorted-wave impulse approximation. Our relativistic calculation using the NN interaction with a pseudoscalar coupling is similar to the nonrelativistic result. On the other hand, the calculation with a pseudovector coupling in the place of pseudoscalar one can give large values of the ratios in the intermediate-energy range from 300 to 500 MeV, but is smaller than the nonrelativistic result and the experimental data in the low-energy range below 200 MeV. This suggests that the important relativistic effect due to the negative-energy contribution may be apparent in the ratio. . by guest on August 11, 2015 http://ptp.oxfordjournals.org/ Downloaded from

“…For this reason the O(a) and leading O(a 2 ) terms can essentially be tuned in-dependently (cf. [7]). By the same token, one can argue that one indeed should tune the O(a) and (leading) O(a 2 ) terms to eliminate the violations of both chiral and rotational symmetry.…”

“…In ''~r(n, p) at small angles, the spin giant-dipole resonance (SGDR) is expected to dominate. For (n, p), the SGDR is calculated to be concentrated in a region 5-7 MeV in width; whereas for (p, n), it is spread over [15][16][17][18][19][20][21][22][23][24][25] MeV, so the SGDR is more easily observed in (n, p). In addition, the GT and isobaric-analog state (IAS) are largely Pauliblocked, so as to permit a relatively unobstructed view of the SGDR.…”

This paper discusses some preliminary results from the (n,p) experiments performed with the new TRIUMF nucleon charge-exchange facility. Data are presented for the 26Mg(n,p), 54Fe(n,p), 90Zr(n,p), and 208Pb(n,p) reactions. For 26Mg and 54Fe, the Gamow–Teller (GT) strength is apparently quenched to the same extent in (n,p) as in (p,n) reactions. For 90Zr and 208Pb, little GT strength is observed in the (n,p) reaction, but 208Pb(n,p) exhibits a strong spin-dipole peak. Some future (n,p) experiments at TRIUMF are briefly mentioned.
