- Gamma-ray lines from Sn-103 have been identified for the first time using EUROBALL and ancillary detectors. The level scheme of Sn-103 has been established by means of particle-gated gamma gamma coincidences. The energy spacing between the g(7/2) and d(5/2) neutron single-particle orbitals is determined from the excited states in Sn-103.

- Excited states of nuclei in the vicinity of Sn-100 have been studied using: the EUROBALL detector array. Gamma-ray lines from Sn-103 have been identified for the first time, and a level scheme of low-lying excited states of Sn-103 has been established. New constraints on energies of single particle orbitals with respect to the Sn-100 core are obtained.

- We report on electrical and magnetic properties of a continuous series of solid solutions La-0.7(Pb1-xSrx)(0.3)MnO3 prepared by the pulsed laser deposition technique on LaAlO3 and SrTiO3 single crystals. Strict compositional control enables us to tailor the metal-to-semiconductor phase transition from 266 to 327 K, the maximum of temperature coefficient of resistance from 10.2% K-1 to 3.2% K-1, and maximum of magnetoresistance ratio at 7 kOe from 41% to 17% for x = 0 and x = 1 correspondingly. The ferromagnetic resonance linewidth ranges from 124 to 300 Oe, indicating low microwave loss and the films uniformity. Noise spectroscopy performed in the 2 Hz-20 kHz range reveals two components: Johnson noise (independent of frequency and bias current) and excess 1/f noise proportional to the square of the bias current. Very low excess noise (normalized value gamma /n varying in the range from 10(-20) to 10(-22) cm(3)) has been achieved due to the epitaxial quality of the fabricated films. Using these films, an infrared radiation bolometer and weak magnetic field sensor have been built and tested. The bolometer resolves the noise equivalent temperature difference as low as 120 nK/root Hz at 30 Hz frame frequency, while the magnetic field sensor shows the noise equivalent magnetic field difference of 50 mu Oe/root Hz at 1 kHz and optimum bias magnetic field applied.
