anomalon

[ə′näm·ə‚län]
(nuclear physics)
A nuclear fragment, produced in the collision of a projectile nucleus at relativistic energy with a target nucleus at rest, that has an anomalously short mean free path, comparable to that of a uranium nucleus.

Four species of Anomalon Panzer, 1804 (Hymenoptera: Ichneumonidae) newly recorded for Peru
The parasitoid wasp genus Anomalon Panzer is a diverse group with a cosmopolitan distribution, and is apparently most species-rich in tropical and subtropical regions (Gauld & Bradshaw 1997).
The aim of the present note is to document the range extension of four species of Anomalon that are now known to occur within Peru.
Anomalon cotoi was only known to occur in Costa Rica where it is widespread, primarily in lowlands from sea level up to an elevation of about 800 meters, and very rarely higher (Gauld & Bradshaw 1997).
Anomalon duniae was only known to occur in Costa Rica where the majority of specimens were collected in middle elevation humid forest sites between 700 and 1600m (Gauld & Bradshaw 1997).
Anomalon fuscipes was only collected in southern Mexico and southwards to Costa Rica.
Jain of the State University of New York at Buffalo, the quarry is an elusive particle called the anomalon, apparently created in high-energy collisions between heavy atomic nuclei and atoms in a solid target.
Doubt cast on the statistical analysis used to establish the anomalous nuclear effect fueled a controversy, and several subsequent experiments failed to detect any evidence of anomalons (SN: 2/25/84, p.
Interest in the topic quickly died down, and Jain became one of the few physicists who remained convinced that anomalons exist (SN: 6/30/84, p.
Jain's idea that anomalons are so short-lived that their paths would be extremely short is a promising approach, says William C.
The existence of anomalons, fragments of atomic nuclei that interact with other nuclei more readily than expected, is a highly controverted topic.
