“…The above results considerably differ from those reported in ref. 2, in which the unexposed part is dissolved in the alkali solution while the exposed part remains, although the composition of WO x is unknown and the deposition conditions differ from those in this study. We presume that the difference in detailed ordering even in the amorphous state caused by different deposition conditions causes the opposite results obtained in both studies.…”

A search for monoenergetic positron emission following the decay of the isomer 1 5 2 m E~ (tl,* = 9.32 h) has been performed using a double-focusing iron-core electron spectrometer. No line was observed at the appropriate point in the spectrum and a consequent branching ratio for this process was determined to be < 3.4 x lo-' positrons per gamma transition. From this result it was deduced that the lifetime of the 15 1 1 keV level in IS2Sm is greater than 3.5 x s.

“…4) It was also shown in ref. 2 that WO x film is available for HMM as a negative-type photoresist material. The negative-type means that the microregion of WO x film transformed by laser irradiation remains and the other region is dissolved by alkali development.…”
