H+ + NO(vi = 0) → H+ + NO(vf = 0-2) at ELab = 30 eV with canonical and Morse coherent states

► First ever utilization of various Morse coherent states in chemical dynamics. ► Single-determinantal level results are comparable to multi-reference level ones. ► Nuclear classical-mechanics results are comparable to quantum VCC-RIOS results. ► Better experimental rainbow angle prediction than that by VCC-RIOS. ► Experimental differential cross sections prediction comparable to those by VCC-RIOS.
