    "abstract": "We present in this paper the general framework of a method which permits to\nrestore the rotational and particle number symmetries of wave functions\nobtained in Skyrme HF+BCS calculations. This restoration is nothing but a\nprojection of mean-field intrinsic wave functions onto good particle number and\ngood angular momentum. The method allows also to mix projected wave functions.\nSuch a configuration mixing is discussed for sets of HF+BCS intrinsic states\ngenerated in constrained calculations with suitable collective variables. This\nprocedure gives collective states which are eigenstates of the particle number\nand the angular momentum operators and between which transition probabilities\nare calculated. An application to 24Mg is presented, with mean-field wave\nfunctions generated by axial quadrupole constraints. Theoretical spectra and\ntransition probabilities are compared to the experiment.",
