abstract = {<p style="text-align: justify;">The ill-posed problems of the identification of unknown source terms in a
time-fractional radial heat conduction problem are studied. To overcome the difficulties
caused by the ill-posedness, a fractional Tikhonov regularisation method is proposed.
Employing Mittag-Leffler function, we obtain error estimates under a priori and a posteriori regularisation parameter choices. In the last situation, the Morozov discrepancy
principle is also used. Numerical examples show that the method is a stable and effective tool in the reconstruction of smooth and non-smooth source terms and, generally,
outperforms the classical Tikhonov regularisation.</p>},
