Marked changes in (p,t) analyzing powers for the isotopes of Zr, Mo, Ru, and Pd and strong, sequential, two-step transfer processes in both (p,t) and (t,p) reactions

Drastic changes of 0/sup +//sub g/..-->..0/sup +//sub g/ (p, t) analyzing powers for the isotopes Zr, Mo, Ru, and Pd are explained in terms of interference between one-step and (p,d)(d,t) sequential transfer amplitudes of comparable magnitudes. Dependence of the analyzing powers on reaction Q values, incident energies, and nuclear structures is interpreted from the interference. Analyzing powers for (t,p) reactions can be understood similarly. A test of time reversal invariance in nuclear reactions with use of the analyzing powers for (p,t) and (t,p) reactions is discussed.
