The He I optical emission spectroscopy that considers the spatial structure of radiation trapping was proposed by us and was applied to a MAP-II divertor simulator. The spatial distribution of the optical escape factor was calculated from the n  (1)P (n≥3) state profiles measured by visible spectroscopy. The profile of 2  (1)P, which is immeasurable by visible spectroscopy, needs to be broader than that of the 3  (1)P state. The sensitivity of the 2  (1)P profile to the T(e) value estimated by He I spectroscopy is investigated.

The plant Paganum Harmala is found in India, Mongolia, northern China, and in the dry range lands of the American Southwest. The seeds of the plant contain the hallucinogenic alkaloids harmine, harmaline, harmol, harmalol, and harmane [1–4]. These alkaloids are also found in the South American plant species Banisteriopis. The hallucinogenic properties of the juice from Banisteriopis plants are employed by several Amazonian Indian tribes to produce visions for ceremonial purposes [1–4]. In addition a similar alkaloid is found in the pineal body [5]. As hallucinogens these alkaloids are reportedly more active than mescaline or LSD [4].
