The Ideal

Abstract Nuclear-state population transfer in the multi-lambda systems with N = 5 that interact with four X-ray laser pulses are investigated theoretically. By using the coincident pulses and stimulated Raman adiabatic passage (STIRAP) techniques, the population transfer from one initially populated ground state to an arbitrary coherent superposition of other ground states. Since the frequency of currently available X-ray lasers is lower than the gamma rays, in this method, X-ray laser pulses with different frequencies are interacting with the accelerated nuclei. We employ the Morris-Shore (MS) transformation to reduce the five-states system to two separate three-state and two-state linkage. The required laser intensities were calculated, which satisfy the conditions of coincident pulses and multi-lambda STIRAP techniques. Considering the spontaneous emission from excited states, the master equation has to be used for numerical study, and it is shown that an arbitrary superposition of final ground states can be obtained. Also, it is observed that by increasing the number of coincident pulses, the population of ground states gets closer to the ideal situation.

Limiting Case

In this work, we study a continuous quantum system of a mixture of bosons and fermions with the supersymmetry SU (m|n). The particles are confined in a harmonic well and interact with each other through the 1/r2 interaction. An eigenstate of the Hamiltonian is constructed explicitly for the most general SU (m|n) case and its energy is given explicitly. It is argued that this eigenstate is the ground state of the system. Moreover, we construct some excited states giving an equally spaced spectrum. In the limiting case where there are no bosons in the system, our results reduce to those obtained previously.

Vuv Spectra

Using R.D. Cowan’s computations (1979) and parametric calculations of Meinders et al (1982), old analyses are thoroughly revised and extended at Aligarh, of Zr III by Khan et al (1981), of Nb IV by Shujauddin et Chaghtai (1985), of Mo V by Tauheed at al (1985). Cabeza et al (1986) confirmed the last one largely.Extensive studies have been reported of the 1–e spectra, Zr IV (Rahimullah et al 1980; Acquista and Reader 1980), Nb V (Shujauddin et al 1982; Kagan et al 1981) and Mo VI (Edlén et al 1985). Some interacting 4p54d2levels of these spectra have been reported from our laboratory, also.Detailed spectral analyses of transitions between excited states have furnished complete energy values for J ≠ 1 levels of these spectra during 1970s and 80s. Shujauddin et al (1982) have worked out Nb VI and Tauheed et al (1984) Mo VII from our lab, while Khan et al (1981) share the work on Zr V with Reader and Acquista (1979).
