| Abstract | Summary. The elliptical galaxy NGC 3962 has been measured in the 21-cm line of neutral hydrogen with the radio- telescope, at three adjacent points along the East-West diameter of the Galaxy, with a distance between successive points of 4'. Its neutral hydrogen mass is equal to 9.4 108 solar masses, which leads to an H i mass to luminosity ratio equal to 0.052. The 21-cm line has a rather large width of about, 510 km 1 The neutral hydrogen has a very wide extent: the H I diameter is 2.7 times larger than the photometric diameter; this property is similar to that found in the elliptical galaxy NGC 4636. The common properties of elliptical galaxies which exhibit a relatively large H I content are discussed: their similarities give a lower weight to the theory of chance encounter between an intergalactic gas cloud and a gas empty elliptical galaxy. Key words: galaxies - elliptical galaxies - neutral hydrogen distribution - interstellar matter - 21 cm line radiation |
