AB: We have performed three dimensional MHD simulations of magnetic reconnection to investigate the structure the fast plasma flow generated by reconnection, so called reconnection jet. Our simulation results show the significantly complicated structure of the front of the reconnection jet. In the randomly perturbed plasma environment, the smaller scale structure develops rapidly and finally, the front of the reconnection jet becomes turbulent state. Then, in the more simple cases that the initial perturbation is single sinusoidal configuration, we found that the smaller wavelength mode grows faster and the magnetic bubbles are generated. The magnetic bubbles elongate as the time development. From the properties of the structure of the jet front, we interpreted basically this deformation of the structure as the excitation of the Rayleigh-Taylor and/or the ballooning mode.
