  We report on high resolution observations of recurrent fan-like jets by the
Goode Solar telescope (GST) in multi-wavelengths inside a sunspot group. The
dynamics behaviour of the jets is derived from the Ha line profiles.
Quantitative values for one well-identified event have been obtained showing a
maximum projected velocity of 42 km s^-1 and a Doppler shift of the order of 20
km s^-1. The footpoints/roots of the jets have a lifted center on the Ha line
profile compared to the quiet sun suggesting a long lasting heating at these
locations. The magnetic field between the small sunspots in the group shows a
very high resolution pattern with parasitic polarities along the inter-granular
lanes accompanied by high velocity converging flows (4 km s^-1) in the
photosphere. Magnetic cancellations between the opposite polarities are
observed in the vicinity of the footpoints of the jets. Along the
inter-granular lanes horizontal magnetic field around 1000 Gauss is generated
impulsively. Overall, all the kinetic features at the different layers through
photosphere and chromosphere favor a convection-driven reconnection scenario
for the recurrent fan-like jets, and evidence a site of reconnection between
the photosphere and chromosphere corresponding to the inter-granular lanes.
