Interferences emerge when multiple pathways coexist together leading towards\nthe same result. A Recent study by Blasing and coworkers [PRL 121(7):073202]\nshowed that in a photo-association reaction of Raman dressed spin orbit coupled\n87Rb Bose Einstein Condensate when the reactant spin state is prepared in\na coherent superposition of multiple bare spin states it leads to a destructive\ninterference between reaction pathways. Here we report a theoretical study for\na reaction scheme which leads to constructive quantum interference. This is\nachieved by changing the reactive scattering channel in the reaction. As the\norigin of coherent control comes from the spin part of the wavefunction it is\nsufficient to use radio frequency coupling to achieve the superposition state.\nOur results show that interferences can be used as a resource for the coherent\ncontrol of photo-chemical reactions. The approach is general and can be\nemployed to study a wide spectra of chemical reactions in the ultracold regime.\n
