Abstract. Efficient programs to calculate two-particle oscillator brackets (or Talmi-Moshinsky-Smirnov coefficients) have been constructed recently, Comput. Phys. Comm. 265 (2021) 108005. The corresponding Talmi-Smirnov transformation is mostly performed in case of particles of equal masses and the constructed programs have been tested in detail as to this case. However, it occurred that those programs included a bug revealing itself in case when particle masses are different. The bug is eliminated in the present version of the programs. All the various tests employed previously at equal masses of particles now reproduce the required results for the case of different masses as well.

Phys. Comm. 265 (2021) 108005Does the new version supersede the previous version?: YesReasons for the new version: Necessity to fix a bug in the programs which affected the brackets in case of the Talmi-Smirnov transformation at non equal particle masses. The author is thankful to M.A. Sharaf who pointed out the incorrect results pertaining to the previous version of the programs.Summary of revisions: The subroutine to calculate the quantity (23) from Ref. [1] is corrected. This quantity includes powers of tanφ where φ is the angle specifying the kinematic rotation. In case of equal mass particles one has |tanφ|=1, see [1]. Most applications of the brackets in the literature refer to this case and the previous version of the programs has been tested at |tanφ|=1. However, the mentioned subroutine included a bug that reveals itself in the |tanφ|≠1 case. In the present version of the programs, the bug is eliminated. All the various tests described in [1] now reproduce the required results also at |tanφ|≠1, i.e., at arbitrary mass ratio of particles.Nature of problem: Single-particle basis oscillator states are widely used for studying the structure of various many-body systems. To compute matrix elements of two-body operators, the Talmi-Smirnov transformation of oscillator states is performed. Coefficients of this transformation are called oscillator brackets. Often it is necessary to retain large sets of basis oscillator states in calculations. Therefore, a fast program to compute the brackets is needed. The program should provide accurate results up to high oscillator excitations.Solution method: At zero radial quantum numbers, oscillator brackets are calculated using an explicit expression that includes few summations. Starting from such brackets, recurrence relations are employed to calculate the brackets of the general type. These relations prove to work perfectly up to very high oscillator excitations.
