The energy spectrum of reconnected vortex loops in He II
A systematic study of the energy spectrum after reconnection of vortex loops was made at various values of the liquid temperature (from a temperature close to absolute zero to a temperature of T = 1.9 K). At each temperature, the initial conditions varied, namely, the vortex loops were initially located in planes, the angle between which varied from 0 to π/2. To find the spectrum, a statistical approach was used, i.e., the second-order longitudinal structural function of velocity was calculated. In all cases considered, the spectra were obtained that are characteristic of a smooth vortex ring.
