"In a previous note a dynamical description of resonance scattering was given, and transient terms appeared in the wave function describing the process. To understand the physical significance of these terms, the transient effects that appear when a shutter is opened are discussed in this paper. For a nonrelativistic beam of particles, the transient current has a close mathematical resemblance with the intensity of light in the Fresnel diffraction by a straight edge. This is the reason for calling the transient phenomena by the name of diffraction in time. The shutter problem is discussed for particles whose wave functions satisfy the Schrodinger equation, the ordinary wave equation, and the Klein-Gordon equation. Only for the Schrodinger time-dependent equation do the transient wave functions resemble the solutions that appear in Sommerfeld's theory of diffraction. The connection of transient phenomena with the time-energy uncertainty relation, and the interpretation of the transient current in a scattering process, are briefly discussed. The relativistic wave functions for the shutter problem may play an important role in the dynamical description of a relativistic scattering process." :: abstract. 3. MOSHINSKY Borodiansky, Marcos.

Transformation Brackets for Harmonic Oscillator Functions. From: Nuclear Physics 13 (1959) 104-116; North Holland Publishing Co., Amsterdam. "We define the transformation brackets connecting the wave functions for two particles in an harmonic oscillator common potential with the wave functions given in terms of the relative and centre of mass coordinates of the two particles. With the help of these brackets we show that all matrix elements for the interaction potentials in nuclear shell theory can be given directly in terms of Talmi integrals. We obtain recurrence relations and explicit algebraic expressions for the transformation brackets that will permit their numerical evaluation" :: abstract. 5.

"The present series of papers will deal with the classification of states of N particles moving in a harmonic oscillator common potential. In this paper we will be mainly concerned with the classification scheme that brings out a collective nature of the states. To obtain this collective behaviour, we take advantage of the invariance of the hamiltonian under both ordinary rotations and the unitary group inN dimensions." :: abstract. 6.

Gelfand States and the Irreducible Representations of the Symmetric Group. Offprint from: Journal of Mathematical Physics, Volume 7, Number 4, pp. 691-698, April 1966. "The set of Gelfand states corresponding to a given partition [h1 . . . hn] form a basis for an irreducible representation of the unitary group Un. The special Gelfand states are defined as those for which [h1 . . . hn] is a partition of n and the weight is restricted to (11 . . . 1). We show that the special Gelfand states constitute basis for the irreducible representations of the symmetric group Sn and use this property to construct explicitly states in configuration and spin-isospin space with definite permutational symmetry." :: abstract. 9. MOSHINSKY Borodiansky, Marcos; Syamala Devi, V. General Approach to Fractional Parentage Coefficients. Offprint from: Journal of Mathematical Physics, Volume 10, Number 3, pp. 455-466, March 1969. Abstract: "The purpose of this paper is to achieve a clearer understanding of the problems involved in the determination of a closed formula for fractional parentage coefficients (fpc). The connection between the fpc and one?block Wigner coefficients of a unitary group of dimension equal to that of the number of states is explicitly derived. Furthermore, these Wigner coefficients are decomposed into ones characterized by a canonical chain of subgroups (for which an explicit formula is given) and transformation brackets from the canonical to the physical chain. It is in the explicit and systematic determination of the states in the latter chain where the main difficulty appears. We fully analyze the case of the p shell to show that a complete nonorthonormal set of states in the physical chain [upsilon] (3)?R(3) can be derived easily using Littlewood's procedure for the reduction of irreducible representations (IR) of SU(3) with respect to the subgroup R(3). This procedure gives a deeper understanding of the free exponent appearing in the polynomials in the creatio.
