Velocity dependence of a #cod#x025B; #cod#x2212; and b the imaginary part of #cod#x03C7; nl for G 2 #cod#x0393; 10 #cod#x003D; 5, #cod#x0394; 2 #cod#x0393; 10 #cod#x003D; 0, #cod#x03B6; 2 #cod#x003D; 1.2, and #cod#x0394; 1 #cod#x0393; 10 #cod#x003D; 3 dashed curve, 3.7 solid curve, 4 dotted curve, and 5 dash-dotted curve. The resonant velocities v #cod#x00B1; correspond to the cross points of the curves #cod#x025B; #cod#x2212; v with a line y #cod#x003D; 0 thin solid line shown in panel a. In panel b the maximum of Im[ #cod#x03C7; nl ] with #cod#x0394; 1 #cod#x0393; 10 #cod#x003D; 5 is normalized to 1.
