During 1999­2006 the second stage of investigation of HI distribution around supernova
remnants (SNRs) was carried out with the RATAN­600 radio telescope. In contrast to
a previous stage during 1985­87 now SNR of large angular dimension (greater than 10 # )
and specific type -- S (shell) were selected, independently from their radio brightness. It is
obvious that namely such objects have su#ciently large ages for demonstrating a evidence of
interaction between their shock waves and surrounding neutral gas. Such a evidence could
be detected in the ``Right Ascension -- Velocity'' (#-V ) maps as ring like structures, whose
parameters may bring information about sizes, ages and energy of supernova explosion.
Now we have observed about 130 SNRs and 105 #-V maps are plotted. Some interesting
objects (such as S147, Cygnus Loop, HB3) were studied in detail and results were published
separately. Soon all # - V maps will be available at our web­site.
