We present spectroscopic and UBV(RI) c JHKLM photometric observations of SN 1987A in the Large Magellanic Cloud made between days 793 and 1770 after the Kamiokande-II neutrino event, as well as some CCD UBV(RI) c photometry from day 640 to day 792, w

A method is described for experimentally measuring the neutron multiple scattering in four vanadium samples of different geometry by means of the polarization analysis technique. The spin-dependent scattering cross section of 51V provides a much more

The design and construction of a new filter method for polarising thermal neutron beams are described. The filter contains polarised 149Sm nuclei which preferentially absorb one of the neutron spin states from the incident beam. The filter material i

Intensity calibrated grazing incidence spectrographs have been flown on three Skylark sounding rockets to record the solar soft X-ray and XUV spectra over a wide wavelength range. This paper describes the instrumentation and calibration procedures, a

A theory has been developed for interpreting the intensity of the 1s2 1S—1s2s 3S forbidden line in heliumlike ions in terms of electron density at the source. In a recent soft X -ray rocket experiment, this transition has been observed simultaneous

AN attitude stabilized1 Skylark rocket was successfully launched from Woomera, S. Australia, at 05.27 UT on March 20, 1968. Included in the rocket experimental payload were two grazing incidence spectrographs2 from the Astrophysical Research Unit at
