A single photoelectric spectral scan of Jupiter in the ultraviolet is presented in the form of a geometric reflectivity. The reflectivity is then assumed to be due to Rayleigh scattering by molecular hydrogen. An upper limit to the amount of molecular hydrogen above the cloud layer of a 11 km atm. is derived.

On a obtenu un spectre ultraviolet de Jupiter (1700-4000 Å, résolution 55 Å) au moyen d'un dispositif photoélectrique. Cet unique document est présenté camme une réflectivité géométrique, laquelle est ensuite supposée due à la diffusion Rayleigh par l'hydrogène moléculaire. On en déduit une limite supérieure de la quantité d'hydrogène moléculaire présente au-dessus de la couche de nuages d'une atmosphère de 11 km atm.

Резюме

Резюме

Получен ультрафиолетовый спектр Юпитера (1700-4000 Å, разрешение 55 Å) при посредстве фотоэлектрического устройства. Этот единственный в своем роде документ представлен как геометрическая рефлексивность, которая, затем, предположена являющейся следствием релеевского рассеяния молекулярным водородом. Из этого выведен верхний предел количества молекулярного водорода находящегося над слоем облаков атмосферы в 11 км атм.
