The method of solving the Hartree-Fock (HF) equations in the Cartesian harmonic oscillator (HO) basis was described in the previous publication, Ref. [1], which is below referred to as I. The previous version of the code HFODD (v1.60r) was published in Ref. [2] which is below referred to as II. The present paper is a long write-up of the new version (v1.75r) of the code HFODD. This extended version is fully compatible with all previous versions.
Information provided in I and II remains valid, unless explicitly mentioned in the present long write-up.
In Section 2 we briefly review the modifications introduced in version (v1.75r) of the code HFODD. In particular, in Section 2.6 we present numerical tests of the code in situations when the iteration procedure does not converge because of a crossing of single-particle levels in function of the rotational frequency. We then introduce a procedure to follow configurations along the so-called diabatic path. Such a procedure was implemented in version (v1.75r), and allows, in many cases, to obtain converged solutions for both crossing configurations.
Section 3 lists all additional new input keywords and data values, introduced in version (v1.75r). The structure of the input data file remains the same as in the previous versions, see Section 3 of II. Similarly, all previously introduced keywords and data values retain their validity and meaning.
